Recently installed Trisquel 5.5 STS on my rig with AMD Radeon HD6670. Obviously, no 3D-accellerated driver for it, so I installed Trisquel in VESA mode. I presume, it is still running in the same mode. I can bear it as I plan to use this rig for typing/watching videos.

However, I can not set any 16:10 resolution because there is no such option in GUI (only 4:3 and 5:4).

I have tried to correct the issue by changing /etc/X11/xorg.conf and /etc/x11/xorg.conf.vesa as follows (changes in bold):

Two questions:
1) Which file should I have changed?
2) What/where should I change in file to get 1680x1050 32 bit 60 Hz (LCD)?

Eagerly awaiting response.

Seems that "bold" have not worked this time. See asterisk sign (*) at the beginning of first inserted line and same at the end of last inserted line.

Is the "radeon" driver completely non-functional with Linux-libre? I would try this driver otherwise ("vesa" may not be able to use any 16/10 resolution).

Magic Banana,
Seems that you are right about widescreen & VESA driver. I have found in Mageia 2 wiki that VESA driver "doesn't support many common widescreen resolution".

As for AMD/ATI driver - it is not functional on my rig, PC never loads into GUI.
