been looking all night and cant find out how or if you can get the settings in the nvidia xserver settings window to load up after boot. i been trying to change the screen resolution to 2560x1440 on my desktop but when i enter them manually and save. when i boot up it resets back to 1920x1080. everytime. I am new to linux just switched a week ago.the default settings only goto 1920x1080.. even in the display settings.so have to keep manually changing them after boot.
Hi jlandy71 and welcome to the forum. What driver did you use and what card do you have ?
Did you save the save the nvidia x server settings ? via nvidia-settings configuration ?
the driver is 470 and i have a rtx 2070
that only goes to 1920x1080. i want to go higher. i looked up how to add it and none seem to work.
I have no luck with nvidia x server settings, when i downgrade to lets say 1080p i get a black screen and need to force reboot.
The only thing i can think of is to save the nvidia x server settings ? via nvidia-settings configuration ?
Or try to follow this guide
yeah i guess i am not allowed above 1920x1080 in xrandr. i get this error sudo xrandr --addmode DP-4 "2560x1600_60.00"
X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 140 (RANDR)

and i even tried your resolution and it says unrecognized option 3840
Use 470 proprietary not 470 propietary (tested).
The 470 tested has multiple issues. It's name is misleading.

If flickering, you may need refresh rate to be 54.95, instead.

Check which driver you are using in the Software & Updates additional drivers tab... if it's is working, i'd prefer to back away slowly...
By the way, you can run
sudo apt clean && sudo apt autoremove
if you want to.

Everything else looked normal except this line ...
dpkg: warning: while removing fonts-symbola, directory '/usr/share/fonts/truety
pe/ancient-scripts' not empty so not removed
That is no problem- it left a font behind.
