Workaround at end of message. I have been experiencing the same bug. After reading this bug report and doing a little experimentation, I can confirm that output (specifically scrolling) to /dev/console triggers the screen shifting to occur. Furthermore, the problem only occurs when /dev/console is connected to the vga console.
Once the problem has occurred, echo -n > /dev/console does not affect the shifting since it omits the carriage return and does not scroll the screen. echo -n "a" > /dev/console Does affect the shifting after being run 80 times, causing the console to scroll. Until a kernel fix is available, I have worked around the problem by adding console=ttyS1,38400 to my kernel boot options (/boot/grub/menu.lst) to prevent all output to the vga console. -- Steve -- (Multiseat) screen shifts when /dev/console written to https://bugs.launchpad.net/bugs/153425 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
