Hi Keith,

Well, doing the reinstall of xserver did not work, but...

I am now running on v460 NVIDIA! This is what I did:

sudo nano /etc/modules

and added this into the file:
nvidia 
nvidia-drm
nvidia-modeset

I went into Driver Manager and installed v460 and I am now where I want to be resolution wise.

Thanks Keith and have a great day! :)

Strange. The modules file normally does not need to get touched unless you are adding not standard modules.

I only have my out of repository motherboard sensors module added and the msr module. Nothing to do with Nvidia at all.

The nvidia drivers are compiled into the kernel and are not added as modules normally.

Anyway . . . . . glad you got it working to your satisfaction finally.

Hi Keith,

Thanks! And thanks for your help! :)

This is the solution I found that worked. Of course, I used a slightly different first command to open the modules file. And I didn't do the third step since he said it wasn't really necessary.

Have a great day! :)

Greetings,

Now What!?!?

I have noticed over the past few days that my "invalid list is growing in number. I have not been able to figure out what is happening by searching the Internet. All I can find is that Lua scripts have something to do with programming. This is my source of confusion:
Reading preferences ended prematurely
Error loading Lua script 'astronomy_parameters.txt': [string "number_parameters: 4..."]:1: '<name>' expected near '4' 
Switching to Parameter File 'astronomy_parameters.txt'

What is it and is there a way for me to fix whatever is causing the errors? As I stated above, I cannot find anything about Lua scripts accept dealing with programming. I'm not a programmer.

[edit1]I found the "astronomy_parameters.txt" file in the Slots directories. This was the first one I looked at in Slot 0:
<soft_link>../../projects/milkyway.cs.rpi.edu_milkyway/parameters-85-4s-bg-set2.txt</soft_link>

The "parameters-85" number changes with each file in each Slot directory. Hope this helps. :)[/edit1]

[edit2]I found the "parameters-85***.txt" file in the "projects/milkyway" directory. I opened it and this is what I see. It is somewhat long:

Siran, think it has to do with this: https://milkyway.cs.rpi.edu/milkyway/forum_thread.php?id=4691

Hi John,

Hey, thanks!

I searched the Internet, but didn't think about the forum here. That is the answer. Most of mine are 85; I saw one 84 so far. I will no longer worry about them. Tom Donlon said something about it and percentages. I have no idea what percentage mine are. This morning when I posted, I had 58; now I have 62, or was it 64. Oh well, memory ain't what it used to be.

Thanks again John and have a great day! :)

Hello Siran,

Before I begin, I would just like to point out that a Lua script is just a file that follows the syntax for the Lua programming language, and is able to be run by a computer that has Lua installed on it.

What you are pointing out is actually correct behavior for the Separation application and not a problem. The output
Error loading Lua script 'astronomy_parameters.txt': [string "number_parameters: 4..."]:1: '<name>' expected near '4' 
Switching to Parameter File 'astronomy_parameters.txt'
is because the program is being passed a parameters (.txt) file and not a Lua file (which it is able to parse for certain things, but I'm not sure that we actually use that capability in this project). It makes sense that it would have an error reading the file as a Lua file, because the astronomy_parameters.txt file is not Lua code, and the program then safely realizes that it is trying to read a non-Lua file and moves on to reading in the astronomy_parameters.txt file.

The astronomy_parameters.txt file is just a file that is organized a certain way and is used to tell MilkyWay@home what bounds it is allowed to search over in its optimization. It is essentially a bunch of numbers that are telling the program "you are allowed to look here for streams".

The problems with validation in stripes 84 and 85 have to do with a cut we have made to the data: there is no data in a part of the stripe, and therefore the algorithm can't tell the difference between a stream that is fit in one part of that missing chunk vs. another part of that missing chunk. This means that when you receive a workunit to validate, you might get a slightly different answer than the person who ran that workunit before you, since your machine doesn't have data in the missing chunk to actually evaluate. This only causes problems when the runs get sufficiently optimized though, and high levels of precision become necessary for validation.

Hopefully this clears up a few things!

Hi Tom,

Back in the 90s I dabbled in programming in B.A.S.I.C (Beginners All purpose Symbolic Instruction Code) and a little C++. To this day I have not heard of a Lua programming language. I have heard of Assembly, COBOL and Pascal and maybe a few others but no Lua. So you can understand my concern with these invalid tasks, which I'm now up to 101. No offense, but the 84 and 85 stripes just seem to be a waste of time on our PCs to even look at them let alone spend time on them and have that time wasted because of a read error for a file not done in another language.

Again, no offense, but your explanation, except for the Lua file not existing and throwing the error, is all Greek to me. ;)

Is there some way that we can get a choice not to run 84 and 85 in the settings? I just did a quick search for installing the Lua Interpreter on Linux Mint. Would that be a better solution to this? I think I just answered that question by re-reading some of you explanation. It's looking to read a Lua script, but the parameter file is the (.txt) file and NOT a Lua file. I believe installing the Lua Interpreter would have no affect. Correct?

I really would like to refrain from getting so many invalid validations though.

Thanks Tom and have a great day! :)

The Stripe 84 and 85 runs have been taken down. The WUs for those runs that have already been generated/not validated will still go out, but they should be all wrapped up in a couple days.

The "error" that you pointed out is actually expected behavior for Separation, and all runs should show those lines in their logs, not just the stripes that are getting validate errors. The validate errors are caused for a completely different reason. It would not help to install a Lua interpreter on your machine.

I don't expect to put up any runs with similar cuts as Stripes 84 & 85 in the near future, and if we eventually do put up more I will ask that we address this validation error problem. I agree that it should not be the volunteers' jobs to help the developers monitor the status of faulty tasks, and I realize that it has become somewhat commonplace in the Separation project recently.

Best,
Tom

Hi Tom,

Cool! The last time I looked, last night, I think I had 115 invalids. I'm now down to 109. When I saw that the number is down, I went through my task list and counted seven 84s and one 85. I knew the installation of the Lua interpreter would do no good. ;)

Thanks for the help Tom and have a great day! :)

Greetings,

Yesterday, I replaced my PCs AiO CPU cooler. The new cooler is a massive dual fan heat pipe configuration. I have one slight problem with it though. Because of the design of the case side panels, I cannot install the glass panel because of the latching system. It hits the new cooler. :-( The new cooler works better than the AiO did.

I watched a preview video of a Corsair case that looks to fix the problem. My current case is a huge full tower case and it weighs a ton. The corsair is a mid tower with lots of room inside. Since my new CPU cooler is also made by Corsair, I checked the dimensions of the case and the glass panel will not hit the cooler. :-) The new case is a Corsair 5000D Airflow Mid-Tower ATX. It's brand new for this year. It replaces the 4000D and fixed a few issues that users had with that old model.

So, some time next week I will be transplanting my PC into the new case where it will crunch happily ever after. ;-)

Have a great day! :)

Greetings,

Aside from one minor glitch (explained in a bit) the PC transplant was a success. Except that I forgot to plug in my keyboard (not the minor glitch), it booted up right off. I ran out of USB connectors so I had to unplug the monitors USP connection and plug in the keyboard. I suppose I could just plug the keyboard into the monitor and plug the monitor back in. I'm not sure how many USB connectors I have on the monitor. I'll have to check.

Now, for the minor glitch. I thought that my rear exhaust fan was not spinning, but it was just an allusion of seeing the grid through the spinning fan. The CPU fans were and are. I checked my other fans and none were spinning. This case has a PWM repeater attached to it so I plugged the PWM connector onto a fan connection on the motherboard. After seeing the fans not spinning I plugged the SATA power connector into a SATA cable and all my fans are now spinning. There are no instructions for using the repeater.

I don't think it would, but does the repeater require both cables to be plugged in, or just one or the other? Would having 5 fans connected to the repeater be too much for it?

Oh yeah, one other weird thing. Normally there are only 2 wires for the HDD LED just like the PWR LED. This case does not have that; it has a cable with a connector that looks like a SATA data connector, but it will not plug into a SATA port; it's tee'd on both ends and it's got a bajillion gold fingers on both sides of the connector; about 10 or 12 on each side. That makes no sense. I'm gonna look on the Internet to see what I can find, but just in case someone here knows about it, you can drop me a reply. :-) I'll see if I can take a photo of it somehow.

This case is SOOOOOO much quieter that my other case was! I can hardly hear it. :-)

Have a great day! :)

Fan controller hubs I am familiar with and am using have two connections, one for SATA power and one to connect to the motherboard cpu fan header.

Also, one port on the hub is usually designated the Master and that port is the one that reports the fan speed you have plugged into it and passed onto the motherboard fan header connection from the hub.

That Master port is what controls the speed all other Slave fans plugged into the controller.

Hi Keith,

The PWM connection has to be on the CPU fan header? I'll have to reposition it then.

As for the HDD LED, I found out that there is no HDD LED on this case. So, I guess I don't have to worry about that. I still haven't found anything on that cable with that weird SATA type connector. Oh well... ;-)

Have a great day! :)

Could it be a sound thing, one of my cases had something like what you are describing and since I don't listen to music thru my pc's I just left it disconnected. If you look on the net you should be able to find the manual and it might show what that plug is for

Hi Mikey,

I just pulled the side panel off and took another look at that cable. It has nothing indicating what it is for. I looked through the glass at the mobo and I have no matching connector on it. But! This case still has the traditional audio connection for the front panel audio out. Unless! This is a new audio cable for an either/or and this mobo is too old to have the new connection. I don't use the front panel audio connector either. I use a wireless/USB headset.

I'll see what I can do about finding out, on the Internet, about this cable. Thanks for the new idea about a manual. :-)

[edit 1] I figured it out. My mobo IS too old and does not have the connection. It's not for a HDD LED, because as I mentioned, the connector has too many gold fingers on both sides. This case has a Type C USB front panel connection. That cable plugs into a USB 3.2 Gen 2 TypeC® Connector on the mobo. Mystery solved. :-) [/edit 1]

Have a great day! :)

No, not necessarily. It is just that most BIOS' will throw a fit if it doesn't detect CPU Fan rpm and will complain about possible cpu damage because of no cooling.

Also, most new BIOS' allow you to specify a four pin fan header to be either PWM controlled or voltage controlled. You just set it how you want.

You could just plug the hub controller master into CPU Aux port for example and set it to PWM mode and tell the BIOS to IGNORE the CPU Fan header for not having any fan plugged into it.

[Edit]
A lot of new cases have auxiliary lighting strips or ambient lighting and have an addressable ARGB connector. It looks like an inline 5 pin connector.

[Edit 2]
If it looks like a mini SATA connector with lots of pins, it could be the USB 3.2 connector.

[Edit 3]
Should have just kept reading. See you figured out it was the USB 3.2 connector.

[Edit 4]
Yes, very frustrating that the newer cases have dropped an LED hard drive activity indicator. My Corsair Air 740 case didn't have a HDD LED. I solved that my making my own LED light and positioned it in the front air filter area so it could be visible at a glance. Grrrr, very stupid design choice in my opinion.

Hi Keith,

I have my new CPU air cooler plugged into the CPU header. I don't think I have anything on the CPU OPT header; I'll plug it in there.

I just found that one of my USB ports is not working on the front panel. So, I guess this will be a good time to check things out. :-)

I haven't been into the BIOS for quite some time so I will check things out there too.

Have a great day! :)

WOO HOO!!! Now you can loop it back on itself and zip tie it there until you decide to get a new mobo someday.

Hi Mikey,

Yep figgered it out! I didn't use you "manual on the Internet" idea though, I came up with another one instead. I went to Newegg and to their motherboard section. Since I knew mine didn't have the connector, I looked at an upgraded version of my motherboard. I just love how you can get a BIG picture by hovering over the original. ;-) I spotted a connector on the board that quite resembled the reverse of my cable connector. I went to the features section and spotted a number on a pic in the exact spot and checked the number description. TypeC connector. Woohoo! Mystery solved! :-)

Now, I gotta make a decision about an upgrade motherboard. The upgraded mobo I looked at only accommodates Gen 8/9 Intel CPUs (I do not use AMD CPUs). Since getting any CPU, or GPU for that matter, is a hit or miss scenario at this point in time because of this STUPIDO scamdemic, I'm inclined to just go toward a Gen 10 upgrade right off. I'll just have to watch to see when they get in stock. ;-)

Anyway, have a great day! :)
