Cintiq 12WX, OpenSuse 11.0, and much pain and suffering

Let that be a lesson to me: Always blog solutions to problems. The cost of doing so is not just time wasted solving things again, but also the frustration of knowing I’d solved the problem before and if I had just taken a few extra minutes to share what I knew… GRR.

When I upgraded to OpenSuse 11 on the desktop at home, I forgot to back up my X11 configuration files: the Nvidia-Twinview-Cintiq12WX configuration I’d laboriously pieced together from fragments on the Internet and lots of troubleshooting.

ARGH.

Anyway, here it is, so I don’t lose it again: my xorg.conf:

Getting back to the xorg.conf above was a bit of a pain. First I needed to get the nvidia drivers working again, which was a matter of adding the repository and downloading the RPMs. Then I needed to get the dual-monitor setup. I was running into all sorts of problems with it, and I must’ve tried configuring TwinView from scratch at least five times. Then I noticed I had an xorg.conf.twinview in my home directory, so I copied that and used it as a basis. Progress! The screen on the Cintiq started working as a proper screen again.

I had been having problems with the wacomcpl in OpenSuse 11 (Error: unknown device “stylus” or it is currently a core device), so I recompiled the drivers from the Linux Wacom Project. While trying to recompile the driver, I discovered that the kernel-source installed on my system… didn’t have the source files. Pfft.

After much poking around, I threw up my hands and downloaded the kernel source code that matched my system, copied the appropriate config file from /boot as the kernel source code directory’s .config, and started “make oldconfig; make”.

After make had set up the directory tree, I switched back to the linuxwacom drivers and ran “./configure –with-kernel= –enable-wacom –enable-hid –enable-evdev –enable-usbmouse –enable-modver –enable-xsetwacom > log”. Fortunately, make and make install proceeded without incident. (After all the false starts I’ve had today, I was glad at least something worked.)

Then it was a matter of more TwinView poking around to get the tablet confined to just one screen instead of being mapped to two. With a lot of fiddling, I finally got it to work.

Now it’s Sunday evening and I’m grumpy from an entire afternoon spent dealing with hardware issues, so I’m in no mood to write our annual updates. I’ll probably feel much better after the Chicken Maryland we’ve planned for dinner, though. =) And after some cat cuddling. Cats are nice and warm.

All that griping aside, I’d still rather use Linux than Microsoft Windows for stuff like this. =)
