On another laptop equipped with an ati video card I updated the kernel first and the problem was not fixed. Afterwards, I updated the packages usplash and libusplash0 (among others) from version 0.5.43 to version 0.5.44 and it seemed to fix the problem. I don't think it is related to any specific video card, I do think it was a problem with usplash (and/or its library libusplash0).
To Sergei: I would suggest you to check the version of these two packages and to try to update them to version 0.5.44. -- [karmic] Text consoles (Fn+F[1-6]) broken, colorful screen, no prompt https://bugs.launchpad.net/bugs/449746 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
