Desktop screen shrunk?

Hi guys....this is a strange one.

I've been running 18.3 Cinammon with no problems whatsoever.

But I fired up the PC this morning and my resolution of 1440 x 900 was as normal......but I've now got two large black edges on the side as it's not adjusting out to my 21" screen.

Start up and login is as normal.....it's just the desktop that's like it. I reset the res to 1920 x 1080 and it fills the screen......but everything is much too small at that resolution.

Any ideas on how to get round this?

As an update to this....I reinstalled the system but no difference.

Tried generic graphic drivers and nVidia but no difference with that.

So I'm out of ideas now.....can anybody advise?

There's not much to go on there ... need proper system info, copy/paste this to the teminal and copy/paste the text output here:

Open a terminal and run: xdpyinfo | grep "dots per inch" && xrandr -s 1920x1080 --dpi 96 Then taken note of the output. You may need to log out then back in to ensure everything reads the new DPI setting. How does everything look? If it's OK, then you're sorted. Keep note of that output, in-case it's not to your liking. For example, here's what I see on my 1920x1080 monitor:

Code: Select all

$ xdpyinfo | grep 96
  resolution:    96x96 dots per inch
    visual id:    0x396
    visual id:    0x496
Sometimes a resolution change messes up the DPI, for some reason. I've also, in the past, had DPI issues when changing display drivers.

I get this: resolution: 96x96 dots per inch but nothing changes besides.

Aaah, strange! So you have the right DPI and the native resolution of your monitor, but still everything is squished, leaving black boxes on the left and right? I'm wondering if your monitor itself has been changed. Maybe have a look at your monitor's OSD.

Nothing has changed on the monitor.....and it reverts to full width if I switch it up to 1920.

Solved! Monitor settings had changed......even though it hadn't been touched. Really bizarre! :!:

Thanks anyway guys!

Thanks!

I've been racking my brains to figure how the monitor settings could have changed without manual intervention.

The only thing I can think of is we may have suffered a power surge when we had a power cut yesterday.
