Hello
I am attempting to add a custom resolution for a display using xrandr and running into problems.
NOTE:
I know the display supports the following resolution mode because the manufacturer has assured me that it does AND I have been able to drive it successfully at my required resolution when connected to an x86 system.
The error I am running into is:
X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 18 (RRAddOutputMode)
Serial number of failed request: 30
Current serial number in output stream: 31
What I am doing is the following:
gtf 1024 768 60
1024x768 @ 60.00 Hz (GTF) hsync: 47.70 kHz; pclk: 64.11 MHz
Modeline “1024x768_60.00” 64.11 1024 1080 1184 1344 768 769 772 795 -HSync +Vsync
sudo xrandr --newmode “1024x768_60.00” 64.11 1024 1080 1184 1344 768 769 772 795 -HSync +Vsync
sudo xrandr --addmode HDMI-0 “1024x768_60.00”
X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 18 (RRAddOutputMode)
Serial number of failed request: 30
Current serial number in output stream: 31
I have googled to try and find an answer but the only thing that I have found that remotely looks like it might work is:
This however is from 7 years ago… so not sure how relevant it is to today…
Is there another way I should be doing this on the Xavier using Jetpack 4.3?
