Changing resolution logs out user (ends session)

First off, I am so impressed by openSuse. It’s just amazing. Thank you all for putting your time and effort into this project! (I hope I will be able to contribute in the future.)

I am new to linux.
Dual boot Windows 8 and openSuse 13.1. xrandr v1.4 and KDE 4.11.2
S7-392 Acer Aspire S7.

If I change the resolution using GUI via Configure Desktop > Display and Monitor > Display Configuration
and then click on any of the various resolutions in the list and then click ‘Apply,’ the systems logs me off. I.e., back to the main login (where you have to put the password to log in).

The same happens when I input the following into the terminal.
Code:

xrandr --output eDP1 --mode 1280x1024

BTW, xorg.conf does not exist in /etc/X11/ (or anywhere else)

Any suggestions? I just want to make the resolution slightly smaller, ex: 1280x1024 (its defaulting at 1920x1080).

Thank you all!

That’s normal these days. Auto-detection suffices for most, but legacy files (for manual configuration) are respected if they exist.

Using the native display resolution will provide the best picture quality. What is is that you’re really trying to achieve. Some users simply want larger fonts or desktop icons. (You don’t need to drop the display resolution for that.)

Thanks for feedback, deano_ferrari](https://forums.opensuse.org/member.php/122-deano_ferrari)

Well, ideally I would like to bump down the resolution slightly. It’s a 13" screen, so things are quite small.
If that proves too difficult, maybe I can just increase the font.

It would be great to get some ideas on what could possibly be causing the log off. Is it common? Has it been reported? I’ve encountered the situation where I had to manually increase the brightness of the screen, because it starts off black… maybe unrelated…

I guess I got a lot of reading ahead of me :slight_smile:
yep.

My advice is to stick with the native display resolution. For KDE fonts and icons can be adjusted via the menu

System Settings >> Application Appearance >> …

  • For fonts, you can ‘Force fonts DPI’ if required. (Choosing a higher value will increase font size.)

You may need to search for similar reports. I’m not aware of this behaviour.

A separate issue - start a new thread and don’t forget to mention your graphics chipset details

/usr/sbin/hwinfo --gfxcard

Thanks deano_ferrari :slight_smile:

AFAIR that’s one of the bugs the shipped intel driver had. It has been reported and is fixed already for a while.

Just install all updates. Apparently you didn’t yet, since you’re still using KDE 4.11.2 as well.
