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).
