Intel graphic acceleration not working with xorg on Lenovo Yoga C630

[mammique]

Hi all, I'm a crouton user, I just tested Gallium Apollo Lake (great work!) because I'd like to switch to native GNU/Linux, but I didn't install it yet because of hardware limitation. I have a Lenovo Yoga C630 (PANTHEON), I installed I MrChromebox.tech firmware with first RW option. Most things seems to work fine, however I see that the graphic acceleration has low performances. I have about 1200 fps with glxgears under crouton/xiwi, but only 60 fps on Gallium.

I noticed the same problem on crouton/xorg (more logs there), I thought it was because of ChromeOS, but maybe not. Do you know how to locate this issue?

Thank you, best regards, and congrats for your work!

Camille.

This mirrors behavior I've seen recently. Debugging various graphical glitches has led me down into acceleration and driver configuration. The above glxgears info is interesting and mirrors my experience.

Does the installation environment include the drivers and configuration you'd require for acceleration to work on that machine? Can someone from the project tell us if the live environment is a valid place to test that?

lspci -vv output for your VGA controller might be helpful.

Hi, sorry for late reply I didn't see the notification. I've posted detailed log here: https://github.com/dnschneid/crouton/issues/4374 Tell me if it's enough otherwise I'll make more. However it doesn't to be and acceleration problem, as glxgears disables high FPS by default, without the restriction I get very good hardware results: https://gitlab.freedesktop.org/xorg/xserver/-/issues/1111

But still I have graphical problem, some graphical toolkits such as Mozilla's (XUL?) and QT sometimes sucks all CPU power, have to kill apps, and sometimes restart X11…

Thanks,

Camille.
