I changed my grub boot options to add "vga=0x323" to them to resolve some issues with corrupted display during startup/shutdown on my laptop.
The next time I booted the system up, I got a warning over the login screen saying
Xfce Power Manager
HAL Daemon not running
The keyboard and mouse are unresponsive. After a minute or so, they start to work and the system functions as normal.
How can I solve this?
