Title: Weird graphics bug in linux.
Post by: Thorn on August 20, 2008, 08:21:16 pm
Seems to be a fault with memory addressing but ey, I blame Khalsa.

Core2Duo E4400
Asus EN7600GT
2GB DDR2 Adata ram
Asus P5N-Sli
Noobuntu
Nvidia 97.31 Drivers ( They are the latest ones that actually work for me. Never had an issue with them in the last year, so this bug is not related to that before you start accusing it)

Solution? (Windows works fine.)

Edit: I'm also now getting Signal 6(Sigbrt)

Received signal 6, exiting...

Do it anyway? If the new ones don't work you're free to downgrade.

i don't think its driver problems to me it looks like you got a bad pk3 in your base folder that replaces are your default textures with something difrent.  GO through all your pk3s and see if there are any maps that you never play and delete them.

+1

Looks like faulty/messed up pk3. Delete all map pk3s and redownload them.

Or don't, that like 3GB of downloads.
Just move them, and if ones dud find out the name of that texture, and search for it.
A lot faster than re-downloading....

Try to reproduce this problem with any compositing window managers (e.g. Compiz) and related special effects turned off.

The GPU is sampling the wrong textures in it's memory, an only NVidia's drivers know how to put textures there and have the GPU sample them. A mere texture replacement would look like... a texture replacement. I would try playing with the drivers - a given driver version behaves differently for different distros, kernel versions, xorg versions, etc. On a related note, what triggered this? Did you apt-get upgrade? System changes since it worked?

i had the same issue when my gfx card fan failed and slowly cooked itself (took off the fan later there was some nice burn marks)

it is probably a driver issue or your card is going.

I had issues when I card was overheating.
It was running at ~100C, so I dismantled it and cleared all the dust out, and its now down to 60.
I then dismantled everything and removed a worryingly large amount of dust.
So before you assume its borked, check the cooling.

I think your computer does not agree with the unlimited BP server you play on.

Overheating lets it load the wrong textures from the hdd?

No, it lets it load the wrong textures from its ram.
Assuming video card ram is used with the same style of caching in unused space, stuff could hang around for a long time.  I somehow doubt tremulous can anywhere near all the ram on a modern graphics card.

after a while it also makes all the models warp and spike and all that when all the coords starts to get corrupt. that was about the time i bothered to look at my gfx card and actually turn off my pc.

I thought bissig or seeeker had a problem like this. Turned out something was wrong with his RAM. He replaced it and it worked just fine, so you may try a memtest86+ test. I know for a fact noobuntu has it listed in the menu.lst.

Nope. I am the guy who gets screwed over by nvidia drivers or kernel updates frequently 8-P Or who does silly things like updating a distro from 9.3 to 10.2 without using the recommended methods (booting from DVD) or using a development version of KDE4.
