[SOLVED] Poor video performance

riganta · 09-10-2011, 04:32 AM

Guys,

I have some very poor video performance which I did not have before.
Just after my install of slackware-1337, I blacklisted nv drivers with drm it worked well. Now my system is very sluggish due to video issue and takes a while to boot. Finally, running a screensaver would trigger seg fault with Xserver, My box is barely usable.

here is the output of /var/log/Xorg.log --> http://pastebin.com/gEjC4SrC

output of lspci -k

00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 18)
Subsystem: Acer Incorporated [ALI] Device 0447
Kernel driver in use: i915
Kernel modules: i915
00:1a.0 USB Controller: Intel Corporation 5 Series/3400 Series Chipset USB2 Enhanced Host Controller (rev 06)

Any help is much appreciated as I can't really decode the Xorg file log.

Regards,

It seems to look all right, collects a lot of 4:3 aspect ratio modes. What's your monitor?

Can you post the output of
glxinfo |grep OpenGL

BTW, you can get into LQ with links-g :-)).

business_kid, thanks for your reply.

glxinfo |grep OpenGL

OpenGL vendor string: Tungsten Graphics, Inc
OpenGL renderer string: Mesa DRI Intel(R) Ironlake Desktop
OpenGL version string: 2.1 Mesa 7.9.2
OpenGL shading language version string: 1.20
OpenGL extensions:

Display is LG

a bit more info.
I have configured X not to start automatically. That is how I like it

I have notice that my issue (sluggish as hell) is also happening in console mode.
So just to recap for clarity
Two symptoms that weren't there before
1 sluggish video output in console mode and when I watch a movie in system OS. So slow that it is barely usable
2 Seg fault when i run some screesaver.

Dont know if you can make any sense of the logs and most of all why suddenly this is happening. It was not the case before. The only difference between before and now is the recent updates for slackware 13.37 64-bit (I doubt any of those updates could be the cause of those issues).
Even if you cannot, I sincerely appreciate the time you are spending reading my post and my logs

Thanks again business_kid

riganta,

Try configuring LILO to boot up in plain text mode and not frame buffer. I think the issue is related to this error in your log

Code:

[ 34715.186] (II) LoadModule: "fbdev"
[ 34715.186] (WW) Warning, couldn't open module fbdev
[ 34715.186] (II) UnloadModule: "fbdev"
[ 34715.186] (EE) Failed to load module "fbdev" (module does not exist, 0)

If text mode is also slow, then you've got a possible hardware fail.

You might also want to reinstall X or the relevant parts, just in case something got buggered.

Some questions:
You have an Intel graphics device, so why are you blacklisting NVidia modules?
Is this an Optimus set up?
If so, this essential information should have been part of your first post and you should try to blacklist the nouveau driver, too.

Also, do you have disabled KMS by any chance? The Intel driver will not work correctly in that case (if it works at all).

Guys,

Thank you so much for taking the time to read my post.

I have been trolling the internet for the past couple of days and found a couple of posts that perfectly describe my issue to the T and most of all, a lot better than I could

@kingbeowulf

Booting in plain text mode makes it a lot better. I can live with that

My second issue as per post above seems a bit trickier.

@TobiSGD

I do not have an optimus card. I simply have an Intel Corporation Core Processor Integrated Graphics Controller (rev 18) (prog-if 00 [VGA controller])

Nouveau driver is blacklisted and drm as well

Kind Regards,

If you have an Intel GPU there is no need to blacklist the modules for NVidia cards. Also, DRM is the graphics acceleration module and the Intel drivers need KMS to work properly. Please check if both are enabled.

Thanks TobiSGD for taking the time to read my posts.
I have rebuilt my X and I am now using xf86-video-intel instead of vesa. I made sure that KMS is activated and it was. It is working a lot better now and usable. It's not like it was before but I can live with it.
My X is still crashing when i run a screensaver but that is ok: Could be worst I guess

below are the links that help me understand a bit better about X and video issue under LINUX for others.

Thanks again for all the help i got and for the time you all took to read my posts. I am putting this post as solved.
