Fudged working Dual Screen setup (nVidia)

[llawwehttam]

Don't know about the dual display but I have seen that compiz error. Thread here: http://ubuntuforums.org/showthread.php?t=1385261

Haven't checked the text files yet, but just done a quick compiz --replace and I get this:

$ compiz --replace

Should XGL be present? Should xset q reveal the location of the log file? Should there be a software rasterizer? And should there be an 8bit GLX pixmap format?

**edit: Something else I'll try later - maybe it's the GTK theme breaking stuff (Shiki-Colors) - shouldn't be, as it's available in normal Karmic repos now, but who knows... ?

...output is normal.
The Shiki-theme...yes,who knows.
If not,llawwehttam's post seems useful..(post #9 of linked thread),

So to clarify, I should try removing my nvidia driver? And would that simply mean re-installing nvidia-glx-185 in Synaptic?

Thanks for all the suggestions!

First I would see if installing the shiki-colors-theme in your vanilla "tester" account causes same error..
edit:
Second I would install the latest nvidiadriver 195.xx (as said before it is real better)...

[NEUR0M4NCER]

shiki-colors makes no difference in the tester account - I even tried mucking about with CCSM settings to try to get it to break, but no 'joy'...

So downloaded the latest nvidia driver, and when I try to drop into Ctrl+Alt+F1 it gives a blank screen...

"So downloaded the latest nvidia driver, and when I try to drop into Ctrl+Alt+F1 it gives a blank screen..."

???
when you try to install it or after installing??

[NEUR0M4NCER]

Sorry, I wasn't very clear. As far as I'm aware, the best way to install the driver is to drop into a terminal and stop gdm from running before you install, but I don't get a terminal when I Ctrl+Alt+F1, so not sure how to go about installing.

[realzippy]

Have you logged out before Altctrlf1?

BTW,if running karmic you can add the 195 driver by:

sudo add-apt-repository ppa:nvidia-vdpau/ppa


and install it:

sudo apt-get update && sudo apt-get install nvidia-195-modaliases nvidia-glx-195

without dropping to shell...

[NEUR0M4NCER]

That sounds a lot easier!

But then:

$ sudo apt-get update && sudo apt-get install nvidia-195-modaliases nvidia-glx-195

E: Couldn't find package nvidia-195-modaliases

So I tried Update Manager, and it's doing some stuff now, including the nvidia195 driver.

[NEUR0M4NCER]

Heh. And now when I do compiz --replace, I get:

$ compiz --replace

Trying again with indirect rendering:

Oh dear.
