I’m running Linux Mint (13/Maya and 14/Nadia) on a Dell M1730 laptop with dual 8700M GT GPUs and a 17" 1920x1200 Seiko/Epson built-in LCD panel.
With the 2xx series drivers, I could change resolutions to any of the standard 4:3/16:9/16:10 VESA/SVGA ones from 640x480 up through the native resolution of 1920x1200.
With the 3xx series (304 and 310), I only have the option of running at the native resolution of 1920x1200. nvidia-settings and xrandr do not allow any other modes to be set, and applications that try to change the resolution report that they cannot do so.
I have also noticed that GPU scaling options are mission from the 3xx series drivers, which is significant to me because my laptop display does not have an OSD for configuring aspect ratio scaling. I am therefore dependent on the GPU to do this for me.
Running a 2xx version is not a viable workaround for this issue, as the Steam Linux beta client requires that I use a 3xx series driver.
Thing I’ve tried, without success:
- switching back and forth between 2xx and 3xx versions using the “additional drivers” and/or “software sources” utilities in Linux Mint. The issue is consistently present with the 3xx versions and consistently non-present with 2xx versions.
- running nvidia-settings as both root and user, and nvidia-xconfig as root, and allowing them to save settings to their respective files. This does not help before or after rebooting.
- using nvidia-xconfig’s --mode parameter to add modes like 640x480 (they still don’t show up, even after a reboot).
