<SOLVED>there is no 1280x1024 resolution in display.

Post by fafo »

hello
I just installed mint and I am having this problem I have a Samsung SyncMaster 753DFX monitor connected with a VGA to DVI adaptor and I have an old AMD Radeon X1550 GPU, the monitor's native resolution is 1280x1024 but the max resolution in the display app is 1024x768 and it shows the monitor as "Unknown" I tried to set the resolution in the terminal using
xrandr --output DVI-0 --mode 1280x1024
but it says
xrandr: cannot find mode 1280x1024
I didn't find any other way to change the resolution so I came here.

Try this
xrandr --newmode "1280x1024R" 119.00 1280 1728 1760 1840 1024 1053 1059 1080 +hsync -vsync
xrandr --addmode VGA-1 1280x1024R
Then go into 'Display' and see if 1280x1024 is available.

it appears that is isn't a permanent fix, after restarting my pc the new resolution disappeared I think the problem is that it isn't recognising my monitor it says Unknown Image what should I do for it to be recognised?

You can put the script into a text file, make it executable and go to 'Startup Applications' and + add it as a startup.
