 Posted: Fri Sep 08, 2017 12:16 am Post subject: [SOLVED] i915 GPU driver/performance issue |
 |
|
Good day,
So the basic issue is horrible performance (even for this GPU - an Intel i915 in a Yoga 2 11). I am a manager on an HL2DM server, so keep this game installed on all of my devices that can run it. This one could play it passably in Winderps with modest detail settings, but haven't tried any other Linux distro, so it could just be a lack-of-support issue.
I assume it has to do with the below weirdness w/ the i965 driver for some reason trying to load, and no evidence that the correct X11 i915 driver loads (but does seem to exist).
| Code: | # glxinfo | grep rendering
libGL error: unable to load driver: i965_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: i965
direct rendering: Yes
# ls -l /usr/lib/dri/
lrwxrwxrwx 1 root root 20 Jul 26 21:15 i915_dri.so -> ../mesa/i915g_dri.so
lrwxrwxrwx 1 root root 20 Aug 23 22:32 i915g_dri.so -> ../mesa/i915g_dri.so

# ls ../mesa

In make.conf I have:
| Code: | | VIDEO_CARDS="intel i915" |
Earlier when troubleshooting, I had some broken symlinks in /usr/lib/dri. One was to the i965 driver. The other two were to some r300 or something...I deleted them, but they should have never existed!! I've never included any reference to this machine since day 0 about i965 or any other GPU that I can remember.
My kernel is configured thusly
Any help is deeply appreciated!

I would think you should be using
VIDEO_CARDS="intel i965"
This should make X11 use the modesetting driver (versus the i965 driver) which should be the most up to date driver.
Make sure you emerge your world again with the --newuse option.

Are you sure about i965? I'm quite certain this CPU has the i915 GPU. My goal would be to get rid of references in X to i965 and get it to load the correct i915 driver I think.
Am I misunderstanding something or is the i965 backward compatible and thus would be the latest for this same chip?
It's a slow machine and that'll be a timeconsuming rebuild or I'd just try it lol
Thank you for the reply!! |

965.
Your CPU is a Baytrail and that has the HD4000 graphics.
The HD4000 is more like the i965 than the older i915.

That did the trick! Thank you very much! I'll update the wiki for this laptop as well.
EDIT: Everything is running smoother now, including the game, which I think is running smoother than I remember on Winderps |
