Laptop display resolution issue
- Login o registrati per inviare commenti
Have just installed Trisquel-mini Nabia on a Toshiba Satellite L505 w/ Radeon Graphics.
Everything is working fine, except that the display is stretched horizontally.
I can't adjust resolution in "Screen Preferences", no other choice than 1024x768.
I don't need to be able to change resolution, I just would like to have the correct one.
Have tried on my own to sort this issue but found no solution and now stuck at this point.
Is there any (simple) way to override this so-called-detected-resolution to 1366x768 ?
Thank you for your help

Hello, I am assuming you are using the LXDE desktop environment so you should be able to change your resoulution in preference/monitor not in `Screen Prefernces` if not can you please share your xrandr and Please share your system info by entering the command inxi -Fxxxmprz
That's a known issue with radeon cards.
You might want to join the research effort, https://libreplanet.org/wiki/Group:Hardware/research/gpu/radeon
But so far, the lack of non-free firmware prevents to have a full set of resolutions.
Regards.
Some Radeons works with the Modesettings driver minus the 3D acceleration.
Edit either /usr/share/X11/xorg.conf.d/10-radeon.conf or /etc/X11/xorg.conf.d/10-radeon.conf:
Section "Device"
Identifier "Radeon"
Driver "modesetting"
Option "AccelMethod" "none"
EndSection
BTW, does anyone remember (or know) if there was a libre
Radeon firmware implementation?
Also, I own an r300 based mobile chipset (RS690), among an Intel desktop. I might try the radeonhd driver.
Maybe the X.Org libraries are too new, but I must try.

EDIT this is bad: https://cgit.freedesktop.org/xorg/driver/xf86-video-radeonhd/commit/?id=7672a6f263d7737ac6f0e0edc8191aff537e9fb7
Also, it doesn't compile, sadly.
