Hi,
I'm having problems running X server on Debian 10 with AMD Radeon RX 5700 XT graphics card.
What I did:
The X server did not start, producing these errors:
Code:[ 96.383] (EE) open /dev/dri/card0: No such file or directory
[ 96.383] (EE) Unable to find a valid framebuffer device
[ 96.383] (EE) Cannot run in framebuffer mode. Please specify busIDs for all framebuffer devicesHere is a full log (/var/log/Xorg.0.log): https://pastebin.com/raw/ebWugwyB
Output of lspci -nn | grep VGA:
Code:0b:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Navi 10 [1002:731f] (rev c1)How can I solve this problem?
Thank you in advance.
