$ xrandr
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1024 x 768, current 1024 x 768, maximum 1024 x 768
default connected 1024x768+0+0 0mm x 0mm
1024x768 0.00*
Here is some of my lspci. As you can see I have Radeon card:
$ lspci | grep -i radeon
01:05.0 VGA compatible controller: AMD/ATI [Advanced Micro Devices,
Inc.] RS880M [Mobility Radeon HD 4225/4250]
01:05.1 Audio device: AMD/ATI [Advanced Micro Devices, Inc.] RS880
HDMI Audio [Radeon HD 4200 Series]
And here is the answer to the topic question. How to set screen
resolutions? Like this:
(define (my-slim-service)
(mlet* %store-monad ((config (xorg-configuration-file
;; #:drivers '("radeon" "vesa")
#:resolutions '((1366 768) (1024 768))
))
(startx (xorg-start-command
#:configuration-file config)))
(slim-service #:startx startx)))
But it won't work for me, because of non-free radeon microcode. If I
uncomment #:drivers line I'll get error like this on X startup:
Missing Free firmware
Failed to load firmware "/*(DEBLOBBED)*/"
