Newbie having issue with display resolution

[Guest]

Hello,

I've an old, but very good, vga monitor that has a native resolution of 1280x1024 at 60Hz, and I can't get Kubuntu 13.10 to see the correct resolution.

I've tried a few things online, but I've got nowhere. The xrandr name for the port is DVI-I-0 as I'm having to use a VGA to DVI adapter to use the monitor. The maximum resolution mode available to the display is 1024x768 and it's getting rather annoying.

My nVidia drivers are installed and working, just besides the resolution.

Any help would be appreciated.

Cheers!

Likely your EDID is not being detected properly. This is common with old monitors. Read through your /var/log/Xorg.0.log to see what's happening.

The best solution is to create an /etc/X11/xorg.conf file with EDID turned off, freqs., DPI, and resolution set manually. Alternate solution; use xrandr's newmode and addmode functions.

Literally 100's of good webpages out there (many of them on this forum) outlining how to do either.

I've tried adding a new mode via the xrandr but I get errors such as this:

X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 153 (RANDR). Minor opcode of failed request: 18 (RRAddOutputMode). Serial number of failed request: 29. Current serial number in output stream: 30.

I'm now trying to update the drivers with ones direct from nvidia, but I'm having difficulty. In order to close the xserver I'm going into init1, but then the installer complains that it needs access to some services in init3 - this loads up x again.

If you install the driver from nVidia's website rather than the repo's you're going to have to go to nVidia's site for support. The Ubuntu package follows Ubuntu file location standards and the nVidia sourced drivers do not. Both will work, but you will have to manually re-insert the drivers into the kernel blob at each kernel update. The Ubuntu packaged drivers use dkms to auto-install with each kernel update almost transparently. Of course, that's your decision but I can see no benefit to it.

If you stick with the nvidia drivers, attach a copy of your Xorg.0.log file to a post and I'll have a look.
