Hi, I am seeing 4k resolution with on dell latitude 7430 model laptop with v11.05.133 firmware on it. I tried multiple resolutions via profiles but nothing works. Can you suggest any?
Have you tried a profile that set the resolution manually for that device?
This works for us when setting the resolution for 4k tv’s for display boards etc.
Hi, in addition to Noahs suggestion: please test latest firmware 11.08.330 since this can also be related to the driver.
# su user -c xrandr –output DISPLAY1 –rate 60 –mode 1920×1080 –fb 1920×1080 –panning 1920×1080* –output DISPLAY2
su: unrecognized option ‘–output’
Usage: su [options] [LOGIN]
-c, –command COMMAND pass COMMAND to the invoked shell
-h, –help display this help message and exit
-, -l, –login make the shell a login shell
–preserve-environment do not reset environment variables, and
keep the same shell
-s, –shell SHELL use SHELL instead of the default in passwd
Open a terminal window and login as `user`
remove `su user -c`
$ xrandr –output DISPLAY1 –rate 60 –mode 1920×1080 –fb 1920×1080 –panning 1920×1080* –output DISPLAY2 –mode 1920×1080 –same-as DISPLAY1
Can’t open display
Run `xrandr`first to find what to replace DISPLAY1 with
Can’t open display
So, you are in front of your IGEL OS PC … You open a terminal window and type in xrandr
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 3840 x 2160, current 3840 x 2160, maximum 3840 x 2160
default connected 3840×2160+0+0 0mm x 0mm
What OS version? `cat /etc/os-release`
My bet is that you will need a newer kernel to support that hardware. I would try 11.08.290
yah it’s 11.05. I will try to upgrade thanks!
