kde system settings > display and monitor > save as default lost after reboot

[MountainX]

I have 3 monitors and I'm trying to save my display settings, but they are lost after every reboot.

I've read about creating an xorg.conf file and also about editing /etc/kde4/kdm/Xsetup. Neither of those sound like the correct approach. Surely there is some way to make the system settings "save as defaults" button actually work like it was designed to work without resorting to a hack. What's the right way to solve this?

If an Xorg.conf is the right way, can someone supply a template?

This info should help:

Something to look/check

When you are saving as default

1) Do you get the confirmation notification ?



2) Is there the ~/.kde/share/config/krandrrc file?

3) Does the krandrrc file have the correct information ?

After the reboot

4) Is the ~/.kde/share/config/krandrrc file still there ?

5) Does the krandrrc have the correct information ?


Manual configuration

Generic: https://wiki.ubuntu.com/X/Config

Today's X rarely requires manual configuration. X now automatically configures itself with reasonable defaults. Both GNOME and KDE provide GUI utilities for customizing settings beyond these defaults if you like.

However, sometimes you need to muck with the configuration manually, beyond what these tools allow...

Thank you for the very helpful reply! That's the best reply I have seen in any of my research on this problem.

I do get that confirmation dialog. And I do have the ~/.kde/share/config/krandrrc file. After I post this, I'll reboot and see if the file is still there.

Here are the current contents, after setting the display configuration the way I want it and saving:

$ cat ~/.kde/share/config/krandrrc

Update: everything is working as it should in Netrunner 4.0.1 64 bit. Previously I tried Kubuntu 11.10 and 12.04 as well as openSuse 12.1 and the display settings were not saved. But with Netrunner it works. I'm not sure why, because Netrunner 4.0.1 is built on Kubuntu 11.10.

Now that I know which files to look for, I'm tempted to reinstall both openSuse and Kubuntu and see if I can isolate the problem. But for now, I will simply use Netrunner because "it just works."

Thanks so much for explaining how this should work. Now I understand what to look for in the future if I have this problem with another distro or version.

You could try a utility called arandr. If I'm not mistaken it lets you save your configuration as a bash script which can be executed either after login or, if you do a bit of research, at the login screen.

I have the same problem, the krandrrc file is there all the time and has the correct info, it just does not exicute. I have to recreate the resolution after every login before it shows in system settings, then it works great untill the next login. But when I navigate to the krandrrc, it is all set just as it should be. I am at a lose to figure this one out, HELP! Here is my krandrrc. [Display]

Possibly the newline part (\n) is the problem. Try

StartupCommands=xrandr --output VGA1 --pos 0x0 --mode 1600x1200 --primary --refresh 59.9988

[oshunluvr]

For MountainX, try creating an executable script separating the xrandr commands into individual commands and add it the to startup script list in System Settings

[oshunluvr]

I noticed on my system /usr/in/startkde contains

krandrrc Display ApplyOnStartup false

changing this to true might solve this for both of you.
