No 3D hardware acceleration on Intel 620 (Lenovo Yoga C630)
Hello, I'm using Linux on a Lenovo Yoga C630. However the Intel graphic acceleration isn't working. I tried xorg server from a traditional Linux distro (Gallium, Ubuntu based), and from an Ubuntu chroot inside ChromeOS (Linux based too), I always get about 60fps with glxgears. But if I run the same chroot within ChromeOS's graphic server (no native xorg, x11 is just emulated by crouton software, running upon ChromeOS's 3D acceleration in a window), I get about 1200fps with glxgears. I guess it comes from the xorg Intel driver, but I can't find any error in the logs. I thought at first it was a crouton bug, or a distro bug, but as I always get the same problem, except when I use xorg, I guess it comes from X11. I filled two issue on crouton and Gallium repositories, with all information listed:
- https://github.com/dnschneid/crouton/issues/4374
- https://github.com/GalliumOS/galliumos-distro/issues/599
Can someone point me to the right direction in order to identify and fix this issue?
Thank you very much!
Bests,
Camille.
