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. |
