A few days ago I installed Ubuntu 12.04 32bit Desktop. It recognized my hardware without a problem (at least that I know of) and all worked fine.
I left my system running (it is at work) through the night because it is also working as a database server and when I came today to work the resolution was
1024x768 (the monitor recommends
1920x1080) even though in the
Display section of the
System Settings it was recognized as
BenQ, and no higher resolution was offered. After a restart, the monitor name changed from
Unknown. This is a desktop computer. I also installed
Additional Drivers to see if there is something I can install but it didn't find anything. I tried to Google it but I didn't find anything about a monitor stopping being recognized after it was already working. I did enable some PPAs yesterday, namely
mozillateam/thunderbird-stable and some other, and I also followed the instructions to patch the
NotifyOSD to be more friendly:
sudo add-apt-repository ppa:caffeine-developers/ppa sudo add-apt-repository ppa:leolik/leolik sudo apt-get update sudo apt-get upgrade sudo apt-get install libnotify-bin pkill notify-osd sudo add-apt-repository ppa:nilarimogard/webupd8 sudo apt-get update sudo apt-get install notifyosdconfig
I now purged both
leolik PPAs in the hope it will help, but no change. Has there been a change in the packages that could introduce this problem?
Any help will be very appreciated :-)
