Title:
Upgrade from 17.10 to 18.04 lost native 3D hardware acceleration for
intel UHD 620, laptop is XPS 9370
Status in linux package in Ubuntu:
Incomplete
Bug description:
Hi,
I did an upgrade via terminal yesterday, everything seemed to work
fine but then I noticed very heavy CPU usage by gnome-shell. The
problem is that the UHD card is not fully recognized, so it uses
instead llvmpipe, so no native 3D acceleration :-( This was working
great in 17.10
Some outputs which might be useful:
______________________________________
sudo lspci -nnk | grep -i vga
-A3 00:02.0 VGA compatible controller [0300]: Intel Corporation UHD
Graphics 620 [8086:5917] (rev 07) Subsystem: Dell UHD Graphics 620
[1028:07e6] Kernel driver in use: i915 Kernel modules: i915
glxinfo | grep llv
Device: llvmpipe (LLVM 6.0, 256 bits) (0xffffffff) OpenGL renderer string:
llvmpipe (LLVM 6.0, 256 bits)
____________________________________
Pls let me know if providing more info would help. I am not sure if
the driver is missing or if XORG is broken, please help. I am using
XORG at the moment, Wayland freezes befpre desktop environment shows
up (it was working in 17.10).
Thanks!
