Troubleshooting Kyral


DVD

Disks aren't being auto mounted and writing is failing. GnomeBaker can blank and burn, but Nautilus fails to identify the CD to write to (only gives an option of writing to file). Auto detection might be because hald is not running? A reboot (071106) fixed all these issues! Why was hald not running?

Some background information:

$ sudo wodim -scanbus

XWindows

After a restart of X11 the mouse stopped appearing. With the nvidia server (rather than nv) the problem was also evident. A reboot seemed to fix the problem.
