I found the cause of my problem! Many people have written that if run the system in single-user mode, and then manually run "gdm" - everything works. I also make this work, and I wanted to find the difference between single- and multi-user modes. And I found the reason - it is a daemon "irqbalance" When I tried to run it manually - the keyboard would freeze after a few seconds. So I just uninstalled it ("sudo aptitude purge irqbalance"). And the system began working perfectly!!!
I have a motherboard ASUS P4S533MX and processor P4 Dariusz Maciejewski, it certainly should work for you. -- [lucid] Keyboard and mouse freeze after grub, usb and PS/2 keyboard not working in X (after upgrade? bad-upgrade to lucid) https://bugs.launchpad.net/bugs/555169 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
