Xinerama and Gnome

jgeboski · March 19, 2009, 12:13am

Hi all,

I am currently having some issues with xinerama and GNOME. When i first boot up and login non of my desktop icons appear but, everything else works fine.

I get the following error:

Xlib:  extension "RANDR" missing on display ":0.0".

I used the handy nvidia settings manager to configure my xorg. If i restart GNOME and log back in my icons show up fine. All help/suggestion welcome.

Thanks,
sloter

in your first post you say “I used the handy nvidia settings manager

which sounds like you fixed your problem…are you now saying that if
you reboot that fix does not persist?

Great Question!

What i mean is when i first boot up and login non of the desktop icons start. If i restart GNOME(ctrl + alt + bcksp) without rebooting the pc it will work. It is just an inconvenience to restart gnome.

Thank again,
James

AH! well, now that i understand your problem i wish i knew the way to
fix it…

hmmmm…i’ve not used Gnome in years but, if you right click on an
empty spot on the desktop, does the resulting menu offer “Refresh
Desktop” or something similar…if you do that do the icons pop up?
does ANYthing change.

how about if you go from one desktop to another?

have you enabled desktop effects or compiz? what happens if you
disable them?

have you used the forum’s advanced search and looked for “extension
“RANDR” missing on display” or just RANDR and done that
reading/understanding…

when you entered
suse “extension RANDR missing on display”
into a google search, did you learn anything useful from the 1,240
(english) hits?

sorry i can’t help more…but, by the way i don’t even know what
xinerama IS, so i obviously haven’t had this problems and don’t plan
to read all those hits for you…but, maybe you will read enough that
you understand enough to help yourself…

for SURE you should read the 6 of the 7 hits from (one is yours, and
you don’t need to read it):
suse xinerama “extension RANDR missing on display”

good luck!!

Nothing happens if i right click on the desktop. It is as if it is frozen almost. No desktop effects or compiz. I have searched around before. I have not found the working solution yet. I will and have have continued to search around and/or hopefully someone post the solution here.

Thanks again for your very useful input!

Strange question but do you have 4 monitors?

I ask this because your xorg has 4 monitors and most of this errors are caused by xinerama.

jgeboski · March 21, 2009, 7:55pm

Yes i do. My apologizes for not stating that. I am also running 2x 8800 Ultras.

Thanks,
James

alexandremrj · March 21, 2009, 8:25pm

I don’t know if you already did it but I recommend two separate things:

Run nvidia settings and when saving to X configuration file remove the check on “Merge with existing file” - do a backup of your Xorg config file. - That way you will have a clean xorg
Remove the RANDR extension on your xorg - it will prevent the changing of resolution on the fly but at least we can try to see if the problem persists.

All the best

Alex

jgeboski · March 21, 2009, 9:36pm

Tired that many times but, tries it again and still no go.
I removed the X RandR parts from my x config file and still no go.

When i type xrandr in xrandr in terminal it says:


Xlib:  extension "RANDR" missing on display ":0.0".
RandR extension missing

Alex thanks for your suggests and help

then you have bigger problems than just with finding and running
Xinerama…

but, did any of the ~5,000 hits from the following help?
suse howto Xinerama

i didn’t read it very closely but the first hit
<http://www.novell.com/coolsolutions/feature/16543.html> did not
mention needing to create a Xinerma icon on the desktop NOR finding
the executable and double clicking on it…
