|# Q: WHY IS THERE A COPYRIGHT NOTICE ON THIS SCRIPT?|
|# A: It had to be added on (a very reasonable) user request.|
|# First we need to get the modeline string for xrandr|
|# Luckily, the tool `gtf` will help you calculate it.|
|# e.g. `gtf <hRes> <vRes> <refreshRate>`:|
|gtf 1920 1080 60|
|# In this case, the horizontal resolution is 1920px the|
|# vertical resolution is 1080px & refresh-rate is 60Hz.|
|# IMPORTANT: BE SURE THE MONITOR SUPPORTS THE RESOLUTION|
|# Typically, it outputs a line starting with "Modeline"|
|# e.g. "1920x1080_60.00" 172.80 1920 2040 2248 2576 1080 1081 1084 1118 -HSync +Vsync|
|# Copy this entire string (except for the starting "Modeline")|
|# Now, use `xrandr` to add a new display mode. Pass the|
|# copied string as the parameter to the --newmode option:|
|xrandr --newmode "1920x1080_60.00" 172.80 1920 2040 2248 2576 1080 1081 1084 1118 -HSync +Vsync|
|# Well, the string within the quotes is the nick/alias|
|# of the display mode - you can as well pass something|
|# as "MyAwesomeHDResolution". But, why though!?!|
|# Then all you have to do is to add the new mode to the|
|# display you want to apply, like this:|
|xrandr --addmode VGA1 "1920x1080_60.00"|
|# VGA1 is the display name, it might differ for you.|
|# Run `xrandr` without any parameters to be sure.|
|# The last parameter is the mode-alias/name which|
|# you've set in the previous command (--newmode)|
|# It should add the new mode to the display & apply it.|
|# If it doesn't apply automatically, force it with:|
|xrandr --output VGA1 --mode "1920x1080_60.00"|
|# That's it... Enjoy the new awesome high-res display!|
|# NOTE to make the change persistent over reboots:|
|# - save the script file (with the necessary changes)|
|# - run it at startup (search the web for "How To")|
|# Thanks for the feedback!|
Hello, I am Tejaswi Gunti..
xrandr --newmode "1920x1080_60.00" 172.80 1920 2040 2248 2576 1080 1081 1084 1118 -HSync +Vsync
Well it seems like you didn't copy the line correctly. It is '--newmode' instead of '-newmode'.
Hi, I got this error in the last step:
nale@r-iibi021:~$ xrandr --output xrdp_0 --mode "1920x1080_60.00"
I googled for a while but found no explanation. You have any ideas what they mean?
@namhoangle from the output name, I'm guessing it's a remote desktop session. If that's the case, see if https://unix.stackexchange.com/questions/90101/xrdp-custom-resolution-fedora-19 helps.
If that's not the case, the simplest assertion would be either
Without knowing more about the relevant details of the system, it'll not be possible to pinpoint the issue.
@teo1978 for a person in their 40's you're awfully bitter. Hope you don't intend to spend the rest of your life as such. I'd recommend taking a moment to self-reflect. And if this seems like an unwarranted/unwanted advice, then congrats... I've been able to get my message across without resorting to passive-aggressive smugness or sarcasm.
If I was facing the same issue as yours, I'd check (in order):
I can't tell which one might be the problem, cause your comment didn't come with any useful diagnostic/troubleshooting information.
