How to set appropriate screen resolution for 19" monitor using xrandr?

mx flag

I'm trying to set custom 1920x1080 resolution for 19" Dell monitor. It's not listed in available resolutions but I know it's the appropriate resolution for this monitor.

I've followed xrandr - fail to set custom screen resolution (Ubuntu 16.04) as well as https://www.tecmint.com/set-display-screen-resolution-in-ubuntu/

my /etc/profile.d/external_monitor_resol.sh contains:

xrandr --newmode "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync
xrandr --addmode XWAYLAND0 1920x1080

then I ran: xrandr --output XWAYLAND0 --mode 1920x1080 and output I got:

X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  139 (RANDR)
  Minor opcode of failed request:  21 (RRSetCrtcConfig)
  Value in failed request:  0x0
  Serial number of failed request:  22
  Current serial number in output stream:  22

Where did I go wrong ?

xrandr works with X11Server not with wayland. Switch over to the XSession (Login Screen) and try again

I stumbled upon this https://www.youtube.com/watch?v=dLVHz7rrP8U guide which led me to solution. Main step was to edit the grub file.

I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
