Public bug reported:
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!
