I found a possible reason of the problem. Installed Ubuntu 11.04 with an other monitor, installation w/o problems. Text mode okay, X okay.
Changed monitor (moved the computer to my normal workplace), booted and saw an error message of my monitor saying "Frequency out of range". Heard hard disc activity and waited until X starts. No problem in X, but whenever I changed to text mode with Alt-F1 to Alt-F6, "frequency out of range". Sounds rather similar to this bug. After digging two hours in the log files, I realized that grub caused the problem. So I added a line GRUB_GFXMODE=800x600 to /etc/default/grub and ran sudo upgrade-grub. Rebooted and the problem was fixed for me. In my problem, grub was the culprit. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/786563 Title: "Input Signal Out Of Range" in textmode -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
