My computer is a former laptop from which I removed the screen. The graphics card is an ATI Radeon of some kind. I have it plugged into a small TV via VGA cable, but Mint still thinks I have the original laptop screen too. The external monitor displays in 1024x768 resolution, but when I use game consoles, and the two times I tested Mageia Linux, it displays in 1280x800 [EDIT: I forgot, it was only the first time with Mageia 1, Mageia 2 didn't suport it]. This resolution is also available for the laptop screen. I want to get the widescreen display to work for the computer, but Mint isn't allowing it.
I've been looking at this page: https://wiki.ubuntu.com/X/Config/Resolution
xrandr -q outputs this (not including the part below about the laptop monitor):
$ xrandr -q Screen 0: minimum 320 x 200, current 1024 x 768, maximum 8192 x 8192 VGA-0 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1024x768 60.0* 800x600 60.3 56.2 848x480 60.0 640x480 59.9
$ cvt 1280 800 60 # 1280x800 59.81 Hz (CVT 1.02MA) hsync: 49.70 kHz; pclk: 83.50 MHz Modeline "1280x800_60.00" 83.50 1280 1352 1480 1680 800 803 809 831 -hsync +vsync
Then I copied that to xrandr, but xrandr didn't like it. When I sudo tried again it gave me this:
X Error of failed request: BadName (named color or font does not exist) Major opcode of failed request: 140 (RANDR) Minor opcode of failed request: 16 (RRCreateMode) Serial number of failed request: 25 Current serial number in output stream: 25
Does anybody know how to fix this?
