Last week Elizabeth took home a fully operational Compaq desktop & TV monitor which subsequently failed to display anything on the screen.
Wiring was checked & ok. It appears that after rebooting, linux mint had reset the monitor resolution higher than the screen (an old Orion TV) could display resulting in a blank display.
Following on from this was a failure to set up wireless dongles (2 different ones tried)
Mint kept misbehaving on each reboot until all the recently available updates were applied, after that, it left the resolution at the chosen setting, and the wireless dongle worked.
Elizabeths next issue was how to Reinstall grub2 from LiveCD, the installation had succeeded but had put the grub boot loader in the wrong place. – This was happening on an HP laptop whose monitor had been vandalised. (see blog from last week).
