xrandr: Configure crtc 0 failed

[rrowles2000]

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.....

Code:

text=$(gtf $1 $2 $3)
search="\""

rest=${text#*$search}
rest=${rest#*$search}

xrandr --newmode $4 $rest
xrandr --addmode HDMI-1 $4
xrandr --output HDMI-1 --mode $4

Usage is therefore...

Code:

bash x.sh 1920 1080  60 "test-0001"

The current mode is...

Code:

Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 4096 x 4096
HDMI-1 connected primary 1920x1080+0+0 (0x43) normal (normal left inverted right x axis y axis) 597mm x 336mm

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....

Code:

test-0001 (0x25e) 172.800MHz -HSync +VSync
        h: width  1920 start 2040 end 2248 total 2576 skew    0 clock  67.08KHz
        v: height 1080 start 1081 end 1084 total 1118           clock  60.00Hz

All the tests I have done 60 odd in total all fail with

Code:

xrandr: Configure crtc 0 failed

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:
