I can confirm this bug on a Toshiba Satellite 3000-X4. Running XFCE with the intel graphics driver.
The only workaround (if you can call it that) is to wait for 10 minutes until the screen is blanked again, then move the mouse. While the screen is black I can't VT switch. Next time it happens I'll ssh in and try and get the Xorg log etc. -- Black screen but everything still work https://bugs.launchpad.net/bugs/123283 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
