Only one low Monitorresolution available after installing Aramo
Hi everyone,
after installing Aramo i am left with only one Monitorresolution available (1024x768) in the system settings.
Everything worked out of the box under Nabia and also the live-USB from which i installed Aramo boots
into the resolution i want (1920x1080). So it should be possible to get it fixed, i just don't know how.
I installed a new kernel (6.12.8-gnu) with no effect.
xrandr output under Aramo:
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 4096 x 4096
None-1 connected primary 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
1024x768 60.00*+
xrandr output under Aramo from live-USB:
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 480, current 1920 x 1080, maximum 1920 x 1080
default connected 1920x1080+0+0 0mm x 0mm
1920x1080 0.00*
1280x720 0.00
640x480 0.00
Any help is appreciated, thanx.
https://askubuntu.com/a/377944 answers "how do I set a custom resolution"... but it does not look normal that 1920x1080 is not listed in the first place.
Thank you for your fast reply.
Searching for a solution i also found that site and tried adding a modeline, it also showed up in the system settings.
Chosing the new mode resulted in an error message.
Just tried it again.
The error message that pops up says: Configuration for CRTC "62" could not be applied
Could you check in h-node.org if the hardware you are using is listed somewhere, using the lspci -vmmnn command seems to be the faster way to search.
If the support is not optimal, it may be an AMD video card we are talking, right?
Sadly those require non-free firmware to enable the device properly.

I don't understand. JohnnyBGood states it worked in the Live session and out of the box in Nabia. Does that mean the Trisquel live-usb has non-free drivers or a different setting is there that could help?
It may be more complicated than saying good old Nadia ISO might have something wrong, AFAIK a device firmware might remain activated even on reboot, that's because of rebooting might not require to cut power energy, so that might be a reason for such behavior.
I'm not saying that it's impossible that the Nabia ISO might had something wrong with it, but at this point in time it's not advised to install a Nabia system as it only will have security updates for a few months.
An Aramo ISO might be a best bet when requiring to install a new system, and even on testing too, but as mentioned earlier it might present the same behavior if the firmware has been active earlier on the same "powered-on session". I doubt a configuration might be the solution as JohnnyBGood mentioned is using the latest Linux-libre kernel 6.12.x-gnu
Aramo received some work to enable a better blob-less support for some AMD models[1] but it's a limited list and 3D is not in the scope of these changes.
Cheers!

Correct, the live-USB works fine as did Nabia.
Anyway the Mainboard is a MSI B450-A PRO MAX with AMD Athlon 200GE Processor.
It looks to me like for some reason the installed version isn't able to detect a monitor. (xrandr lists None-1 as output/monitor
while under the live-Session xrandr has Screen-0 as output/monitor)
