Switch to a text console (Ctrl+Alt+F1) also does not work? Note: Ctrl+Alt+Backspace is in Xorg disabled by default for a long time. (In reply to Slávek Banko from comment #1) > Switch to a text console (Ctrl+Alt+F1) also does not work? Didn't work (and neither Ctrl+Alt+F2, ...+F3, ...). Nor did Ctrl+Alt+Esc switch to a kill-cursor (in the hope of killing the potentially focus grabbing application). Keyboard (internal notebook keyboard -- so no cabling issues) and mouse (both touchpad and USB mouse) very completely "dead": no mouse movements, no key entry into password field. As written originally: no reaction at all! > Note: Ctrl+Alt+Backspace is in Xorg disabled by default for a long time. Not here. Sounds like a kernel bug to me. I encountered a similar situation 3 years ago. I was running 3.2.0 on Debian and there was a bug in the intel graphic card driver in the kernel. From time to time the computer would freeze completely: no mouse, no keyboard, nothing. Thomas, does the "Raising Elephants Is So Utterly Boring" work? (In reply to Michele Calgaro from comment #3) > Sounds like a kernel bug to me. I doubt this on the following grounds: * it is not happening at all with any of the other GUIs I'm testing as substitute for KDE -- which covers at least 3 to 4 times the running time of TDE. * it just recently happened with TDE when executing '/opt/trinity/bin/konqueror', just when the window was painted > I encountered a similar situation 3 years ago.

Sounds like what I experience -- but only under TDE. Perhaps some TDE-specific way of graphic lib calls? > Thomas, does the "Raising Elephants Is So Utterly Boring" work? Should it work? (SysRq is normally deactivated on my traveling machines (like the one I test TDE on), as the disks are encrypted and I don't want to allow peeking into memory and retrieving the disk keys via SysRq!) I was experiencing similar lock of the screen without an option to unlock. Sometimes it wrked with CTRL+Alt+F1, sometime it didn't. Since I switched to a single one - specific screen saver, the issue was not observed anymore. I hope this helps There has been some work done on kdesktop lock process from the time the bug was reported, so perhaps whatever was causing this bug is now ok. Slavek and I are not able to reproduce this bug at all and never ran into the reported issue. We are closing the bug as resolved for the time being, but if anyone runs into the same problem again, please reopen it :-) |
