Description: | |
I just received a wide screen with a 2560x1080 resolution but xrandr | |
wasn't allowing me to use it. The intel graphics specifications say | |
that I should be able to go up to 4096xsomething so it's a software | |
problem. | |
Generate the informations you need with the **gtf** command: | |
$ gtf 2560 1080 59.9 | |
Keep the numbers after the resolution name between quotes, so in | |
`Modeline "2560x1080_59.90" 230.37 2560 2728 3000 3440 1080 1081 1084 | |
1118 -HSync +Vsync` | |
keep only `230.37 2560 2728 3000 3440 1080 1081 1084 1118 -HSync | |
+Vsync` | |
Now add the new resolution and make it available to your output | |
(mine is HDMI2): | |
$ xrandr --newmode "2560x1080" 230.37 2560 2728 3000 3440 1080 1081 | |
1084 1118 -HSync +Vsync | |
$ xrandr --addmode HDMI2 2560x1080 | |
You can now use this mode with arandr using the GUI or with xrandr by | |
typing `xrandr --output HDMI1 --mode 2560x1080` | |
You will need to set the new mode each time the system start. I added | |
the 2 lines in my ~/.xsession file which starts stumpwm. |
