Bug#586502: nvidia-glx: Xorg doesn't try to load nvidia driver even though all other drivers have been removed
Hi,
Russ Allbery r...@debian.org (27/06/2010):
It would be nice if this were restored, since this is the cleanest
way.
looking at the only user of PCI_TXT_IDS_DIR/PCI_TXT_IDS_PATH, the
comment right above the function is:
| #ifdef __linux__
| /* This function is used to provide a workaround for binary drivers that
| * don't export their PCI ID's properly. If distros don't end up using this
| * feature it can and should be removed because the symbol-based resolution
| * scheme should be the primary one */
| static void
| matchDriverFromFiles (char** matches, uint16_t match_vendor, uint16_t
match_chip)
| { […]
Maybe there's something that {sh,c}ould be improved on the binary
driver side? In any case, you may want to check with upstream
(xorg-de...@lists.x.org) whether restoring PCI_TXT_IDS_DIR is really
the cleanest way. I guess I could start that discussion, but I don't
care enough about non-free stuff to do so.

This should probably go into a separate bug report, and I don't think it's nvidia-glx fault if something does not honour the blacklists. Well, sadly, the blacklist doesn't say to never load the module at all, even if explicitly requested, just not to automatically load it based on detection of particular PCI IDs. I'm not sure there's any way to say not to load it at all. I still agree with Andreas's conclusion here. I'm just not sure there's any reportable bug here at all. X.org (somewhat rightfully) favors the non-proprietary drivers. I think at the end of the day we're stuck with documenting required manual configuration to use the NVIDIA drivers. Unfortunately Xorg has no way to easily make it aware of additional drivers (there was a possibility once to drop a list of pci ids, but this is no longer enabled in the debian xorg build), so autoconfiguration does not work and you'll have to create a small xorg.conf. It would be nice if this were restored, since this is the cleanest way. I wonder if Ubuntu is doing something different there. I see that they have a completely different way of packaging the NVIDIA drivers. (They also seem to include all the variants in a single package.) -- Russ Allbery (r...@debian.org) http://www.eyrie.org/~eagle/ -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

Olivier Mehani wrote: When using the nvidia-glx driver on a machine which xserver-xorg supports nouveau, Xorg tries to probe all the non-proprietary drivers that have been built-in (and provided by xserver-xorg-video-all). This includes, in this order, nouveau, nv, vesa and fbdev for my video card. Xorg is not aware of the proprietary drivers, so autoconfiguration does not add them to this list. Despite the blacklist added by nvidia-kernel-common to fix bug #580894, Xorg's probing nouveau does load the kernel module, along with the already loaded proprietary nvidia module. This should probably go into a separate bug report, and I don't think it's nvidia-glx fault if something does not honour the blacklists. The solution I found to that was to uninstall all non-proprietary Xorg video drivers mentionned earlier, to leave a clear spot for the proprietary one. However, X still didn't load as it was sequentially trying to load these drivers (and fail as the files weren't there anymore). X eventually exits without trying to load the nvidia driver. Unfortunately Xorg has no way to easily make it aware of additional drivers (there was a possibility once to drop a list of pci ids, but this is no longer enabled in the debian xorg build), so autoconfiguration does not work and you'll have to create a small xorg.conf. It appears that adding a snippet of Xorg.conf in /usr/share/X11/xorg.conf.d/ (e.g. 99-nvidia-glx.conf) makes X aware of this other driver. Unfortunately this breaks the X configuration if nvidia-glx is installed but no hardware/kernel module is available. I also couldn't find a solution to override this file with an /etc/X11/xorg.conf. So adding this snippet causes more trouble than it solves. The attached 99-nvidia-glx.conf is not really a patch, but I suspect that if the nvidia-glx package provided such a file (maybe with a simple debconf script to enable/disable it), it would solve a lot of troubles trying to install this driver. Please read the README file, it instructs you how to setup your xorg.conf to use the nvidia driver. This is nothing that can be automated that easily, especially if you want to use TwinView or other features.
