disable kde 4 desktop effects while booting

[Guest]

hi.

i tried to activate desktop effects and the whole screen went blank. so i pushed escape and then went to change the advanced settings to see if that would help. nope still blank screen but it didn't automatically go back to default.

now when i boot into kde4 i get the login screen but after the loading icons come up the screen goes blank.

so my question is how can i disable desktop effects before i log in? I tried all recover options in grub boot up menu - but nothing helped.

please help if you have the knowledge. thanks

Boot into recovery... to the command line.

Type the following (replacing "[yourname]" with your user name, of course):
nano /home/[yourname]/.kde/share/config/kwinrc

Find the this line under the heading "Compositing":
Enabled=true

Change it to:
Enable=false

Then press Ctrl+X. Press Y. Press Enter.

Type:
reboot

And then log into KDE normally.

kwin is the part of kde which handles desktop effects. so this fix turns desktop effects off. however, you do this from recovery mode at the command line because the kwinrc settings are not already loaded.

Does this mean compiz will not work again? How can I get it to work again? Thanx

I was actually curious about this as well, I had the same general problem happen. It started when I decided to update some packages this morning. When I rebooted and logged in my screen went black. I can see the "glowy" outlines of what's supposed to be the last 2 applications I had running before reboot. No text, or anything.. and at current I can't seem to get my frame-buffer situated either. Which means i do not have ctrl-alt-f1, and I cannot login to console from the login screen either.

This fix did work for me, but then I tried to restore my kwinrc file back to what it generally was before i rebooted initially, and I get the same "black screen" result. Does anyone actually know what it is that broke here? Just seems to me that disabling something that used to work 5 minutes ago is kinda a poor way to "fix" something.
