Public bug reported:
It seems like every Ubuntu release breaks my quad monitor setup....
I have two GeForce GT 520's and am running 4 monitors, 3 HP S2031's and
one Westinghouse L1975NW turned 90deg. This was working fine with the
current LTS. I decided it was time to upgrade my desktop, as I've been
running 13.04 on my laptop for a month now (started in beta) with no
issues. Here are the steps that have brought me to this point:
1. After installing a fresh cut of 13.04, I was left with 2 HP's on a
single 520 card mirroring eachother (Not uncommon to start out this way,
all the way back since 10.04). I opened display settings and saw it
detected all 4 monitors right off the bat. I got excited... first time
this has happened. I unchecked "Mirrored" and it enabled all 4 monitors.
After a restart, it kinda worked, but the contents monitor 3 & 4 kept
swapping back and forth, so if I drug a window over to monitor 3 it
would jump between 3 & 4 rapidly... this continued even if I drug it
over to monitor 4.
2. I disabled this and went to software & updates and additional drivers
and chose the latest nvidia driver & restarted. Still no luck, and still
no Nivida-settings. Oh, and after trying to tweak the settings a bit
more, I ended up in a login loop. I would login, the screens would go
black and kick me right back to the login page. I could get into the
guest account no problem. I ended up having to delete a config file
(after backing it up... not remembering which atm) in order for unity to
regenerate the default of that file and allow me back into unity without
the login loop.
3. I downloaded the latest nvidia drivers from nvidia's site
(nvidia-313-updates) and followed their instructions for installing.
Rebooted, and behold, I have two monitors working in twinview. I backed
up my xorg.conf and opened nvidia-settings. I configured all 4 monitors,
applied settings, saved settings and restarted. I was excited to see all
four monitors working for the login screen! ... then I logged in and
Unity no longer opens. I ctrl+alt+f1'd and restored my xorg.conf and
restarted. I have since tried several times to make this work, and every
time, unity will not launch.
I, like may others I am sure, am a web developer and multi-monitor is a
key to huge productivity gains for me. I don't want to have to go back
to LTS, I am loving some of the newer 13.04 features, but I need this to
work!!!
If anyone has any other suggestions, or even a video card recommendation
(sub $200) that will support 4 monitors and not die and leave me
stranded with every OS update, I am all ears!
