Hi,
I've been grinding away after 23 years away from Unix trying to 86 windows from my life.
So Far I've got Armbian/Ubuntu/Mate working overcoming various issues along the way.
This is a solid 6 days now and I'm stuck so if someone could point me in the right direction I'd really appreciate it....
I'm using an iiyama E2783QSU on HDMI-1, and trying new modes using xrandr
After getting seriously bored manually going through the options I wrote a little script to help.....
Usage is therefore...
The current mode is...
but if I try to create a duplicate mode or a higher res mode I just get an error but as you can see below "gtf" is not creating a matching mode to the current one that is working....
All the tests I have done 60 odd in total all fail with
I am probably doing something obvious wrong but to be fair I am now losing the will to live
If anyone can help point me in the right direction on this extensive voyage of discovery I would really really appreciate it. :pray:
