Version: (using KDE KDE 3.5.5) Installed from: Debian stable Packages Reported in Debian BTS at http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=380544 I have wondered why my screen sometimes blanks after 5 minutes even though power management is set to 30 minutes. I found out that i had the 5 minutes set up in the KDE screensaver-dialog, but that the screensaver itself was disabled. Using "xset q" i found out that after changing that value to (lets say) 20 minutes the scrensaver values are correct: Excerpt from 'xset q' --------------------- Screen Saver: prefer blanking: yes allow exposures: yes timeout: 0 cycle: 600 --------------------- (to change the value i had to activate the scrensaver, change the value, then deactivate it again) If i now lock the screen of my computer with the KDE-lockicon in the taskbar the screensaver comes up (as configured and expected). But after unlocking the screen the screensaver somehow has read its timeout-value from the config-file, even though it is still disabled: Excerpt from 'xset q' --------------------- Screen Saver: prefer blanking: yes allow exposures: yes timeout: 1210 cycle: 600 --------------------- The timeout-value in the X-Server will return to zero if you change the timeout in KDE as described above. The workaround is obvious: set the timeout to a value that will not disturb you (like 240 minutes, your eyes would be squares by then ;-) but it irks me and may confuse people, hence i reported that little bug...
(Disclaimer: I cite KDE versions below. From my memory. I'm terrible at remembering numbers, they can be wrong by magnitude of 10.) I can confirm this. It happens on my two PCs since forever (it was intruduced in KDE 3.5.0 or one of the first versions afterwards). I was about to post a bug report, as I was able to find a way to reproduce it, until I found yours. I'm using Gentoo, and the bug was fixed in a patch that the ebuild for KDE was applying in KDE 3.5.4, but the patch was removed, and I didn't have time to adapt the patch for newer versions. It renders my desktop PC completely unusable after locking, as it sets the screensaver timeout to 9 seconds. It doesn't matter what KDE screensaver is configured to, it simply does so. I tried setting KDE screensaver to 357913941 minutes, and it still happens. Here is output from 'xset q' before and after locking: On my desktop PC (x86): $ xset q > 1 $ xset q > 2 $ diff 1 2 12,13c12,13 < prefer blanking: yes allow exposures: no < timeout: 0 cycle: 600 --- > prefer blanking: yes allow exposures: yes > timeout: 9 cycle: 600 On my laptop PC (x86_64): $ xset q > 1 $ xset q > 2 $ diff 1 2 12,13c12,13 < prefer blanking: yes allow exposures: no < timeout: 0 cycle: 600 --- > prefer blanking: yes allow exposures: yes > timeout: 310 cycle: 600
Another note, I was using Slackware on my desktop before. The 9 seconds thing is from there.
Ok I just "fixed" this on my desktop, KDE 3.5.7. Setting the timeout to "6001 минута" fixed it. I was trying to set it to "600", but the input box doesn't work and it does append the string "1 минута" to any value I enter.
fixed for kde 4.0 and 3.5.9
