I'm new to Linux, and I just installed elementaryOS. The first thing I do is change the resolution to 1680 x 1050 so that I can see things properly, but when I reboot, the resolution is set back to 2256 x 1338. How can I change it permanently so that it doesn't change? I've heard of using a tool called xrandr but I'm still new to Linux and can't figure out how to use it. Please help!

Open the terminal and type:
sudo vi /usr/sbin/lightdm-session Here is how the first part of that file looks now:
#!/bin/sh # # LightDM wrapper to run around X sessions. echo "Running X session wrapper" # Load profile for file in "/etc/profile" "$HOME/.profile" "/etc/xprofile" "$HOME/.xprofile"; do if [ -f "$file" ]; then echo "Loading profile from $file"; . "$file" fi done -- Here add the xrandr settings # Load resources Press INS (insert) button or i on your keyboard. This will go into the insert mode and you can use go to the end of the line , press enter and put the content I described below.
Copy below:
xrandr --newmode "1680x1050_60.00" 85.25 1680 1368 1440 1576 1784 1050 768 771 781 798 -hsync +vsync xrandr --addmode CRT1 1680x1050_60.00 xrandr --output CRT1 --mode 1680x1050_60.00 Paste into the file with the right button of the mouse, where I marked it with this section:
-- Here add the xrandr settings Press Esc button on your keyboard. Then type :x to save and exit. Restart the Elementary OS. Check does it work.
- I did what you explained, but when I copy pasted, I replaced "CRT1" with the name of my display, but when I reboot, the display resolution is still 2256 x 1338.pbhak– pbhak2020-10-17 19:13:56 +00:00Commented Oct 17, 2020 at 19:13
- Try to replace CRT1 with LCD1 and then check.user19988– user199882020-10-18 07:07:45 +00:00Commented Oct 18, 2020 at 7:07
- Unfortunately, that doesn't do anything. I tried checking the file for errors, then switching from CRT1 to LCD1 and back. But the resolution always resets when I restart.pbhak– pbhak2020-10-20 03:17:31 +00:00Commented Oct 20, 2020 at 3:17
