Failed to get gamma size for single monitor default output

th flag

i am on ubuntu 22.04 for almost 3 months. I'm a beginner in linux. So far, no problems have been found. Until in the end I kept my computer in my storage room for 3 weeks, and then I started it again. This is where the problem starts, where the desktop screen becomes large and there is only 640x480 resolution.you can see here

i type xrandr in cli and output like this:

xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 480, current 640 x 480, maximum                
640 x 480
default connected primary 640x480+0+0 0mm x 0mm
640x480       73.00* 

I've tried to find various ways that I found on ubuntu ask. started from changing to gdm3, etc., but this still doesn't work.

i am using nvidia geforce gt 730 and found no problems before i kept my computer in storage for 2 weeks and when i restarted it i had this kind of problem.

does anyone know how to solve it. I'm still a beginner. I will be very grateful to anyone who can help me.

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.
