Another X-server transition coming up

Re: Another X-server transition coming up

It seems that the new Xserver-xorg is still not compatible with the latest VirtualBox GuestAdditions, so I still can't get my Maverick guest OS out of 800X600.

Re: Another X-server transition coming up

I guess I should assume this is the reason I've lost OpenGL support in Xorg with my Nvidia drivers (kernel module loads, GLX fails in Xorg log)?

Re: Another X-server transition coming up

Not if you are running in a real (as opposed to virtual) system. OpenGL is working fine here. This is 64-bit, dual 9800GT cards, 256.44 driver.

From Xorg.0.log:

Hmm... well that is strange....

Re: Another X-server transition coming up

Have you blacklisted the Nouveau driver? It is apparently bundled in with the kernel for Maverick, and it will definitely zap your NVIDIA driver if you don't blacklist in /etc/modprobe.d. I don't believe the Nouveau driver supports OpenGL at this point. See if there are entires for NOUVEAU in your Xorg.log.
Also I am using the proprietary driver from the NVIDIA website. What may be going on with nv, I don't know.

Re: Another X-server transition coming up

It is possible that the nvidia driver you are using is not compatible with the kernel. Is it new?

Re: Another X-server transition coming up

Doctordruidphd:
When I lost GL initially, nouvea driver was being loaded (a few days ago). So I blacklisted it. Then re-installed the Nvidia drivers (proprietary through apt) to make sure it was fresh and I wasn't missing any files etc.

I tried downloading the latest from Nvidia directly 256.44, which installed fine, but still no GL

GreyGeek:
According to Nvidia, >=2.4.7 is required and I have 2.6.35. Also, I would assume the kernel module wouldn't be loaded if it wasn't compatible, which it is.

If I run the 'nvidia-xconfig' script, it writes a new xorg.conf file, then when I restart Xorg, the 'helper' tells me the video settings are incorrect and to choose from a list of options (low graphics mode, re-detect hardware, etc.)

It's strange, there's a conflict somewhere, just not sure where.

Re: Another X-server transition coming up

Did you run sudo update-initramfs -u? Nouveau embeds itself in the initramfs, so you have to do this after blacklisting it.

Does nvidia-settings give any clue under the "OpelGL/GLX information" section?

Re: Another X-server transition coming up

Doctordruidphd:
I have tried updating initramfs before, but I did again to make sure. The problem doesn't seem to be the kernel module since it loads fine. The problem seems to be with the GLX and Xorg part. Possibly I'm missing a package that got lost during an update?

Installed for Nvidia I have:
nvidia-185-kernel-source
nvidia-185-libvdpau
nvidia-185-modaliases
nvidia-current (dummy package)
nvidia-current-dev (dummy package)
nvidia-current-modaliases (dummy package)
nvidia-glx-185
nvidia-glx-185-dev
nvidia-settings

I am at a loss.

Re: Another X-server transition coming up

I'm not sure what is going here, either. There MIGHT be some conflict between the repository and the proprietary version of the drivers. I know that when I wanted to try the repo version, I had to do a lot of hunt-and-kill for various nvidia files before it would work, and even then it wasn't very stable. Maybe you need to do something like that -- do a delete-and-purge on all the installed repo files, then manually go through and find all the nvidia files a delete them, then reinstall whichever you want to use -- repo or downloaded -- but only one of the two.

Although OpenGL seems to be working here, I have noticed some other bizarre effects. When I try to change colors, fonts, themes, or anything like that, I get what looks like static all over the screen, so bad I have to shutdown. Last time that happened, it was a failing video card, but this time it is doing it only on Maverick, not Lucid, nor Sidux, nor Debian, so I suspect there is still something strange about the video somewhere. I also notice that kdm is behaving strangely -- on the greeter, I no longer see my default name in the login box, but I have to either type it, or click the image to get it. And the "restart X server" option is gone. Maverick is still alpha soup, no doubt.

That being said, there is still something odd about your video problem. I guess I would start by purging and reloading.

No point in bogging down this discussion, since I'm sure now it's not related.... so I started a new topic:
