Hello,
Last week I installed Debian 13.1 on a new machine.
I have problems with the graphics part: X launches, provides basic
functionality, but it is unstable.
Copy-pasting a couple dozen lines from one xterm to another reliably
crashes X.
Opening a new tab in Firefox sometimes crashes X too.
Besides, xrandr offers no resolution higher than 1920x1280 whereas the
screen's native resolution is 2560x1440.
All this may be linked to the fact that there is no separate graphics
card, only a chipset integrated into the CPU.
I hoped this choice would provide silence at a fair price, but it may be
bringing chaos instead.
lshw suggest that Linux recognizes that there is an integrated chipset:
*-cpu
description: CPU
product: AMD Ryzen 7 8700G w/ Radeon 780M Graphics
*-display
description: VGA compatible controller
product: Phoenix1
vendor: Advanced Micro Devices, Inc. [AMD/ATI]
"Phoenix1" seems to be the name of the architecture used by AMD for its
integrated graphics chipsets in Ryzen 7 processors.
I followed the steps from the wiki:
https://wiki.debian.org/AtiHowTo
~> lspci -nn | grep VGA
78:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc.
[AMD/ATI] Phoenix1 [1002:15bf] (rev 06)
I purged '*nvidia*' and installed firmware-amd-graphics etc.
radeontop says the chipset is named UNKNOWN_CHIP.
The problems remained after a reboot.
Am I missing something?
Have I done something obviously wrong?
Is it logical to suspect that the driver may be unreliable?
If so, how can I change it for a proprietary driver?
Any idea welcome :-)
Sébastien.
