hack the planetvideo subsystem
Well shit, it's been about 18 months since my last post. Here's one that'll bore you!
In Debian Wheezy, xorg is now version 7.6 and xserver-xorg-core is version 1.11. With this update comes an increment to the xorg input ABI and the xorg video ABI.
That's great unless you're using a binary driver that hasn't been updated to work with the ABI (NVidia legacy, I'm looking at you). In my case, I've got a Quadro FX 3000 in one of my boxes, and it still needs the 173.xx driver. What to do?
My solution is a hack, plain and simple: downgrade xserver-xorg-core to 1.10 without downgrading anything else. However, you have to be a little tricky about this because otherwise apt will complain that your X install is broken. Here's what you do:
- Grab xserver-xorg-core_1.10.4-1ubuntu5 from the Ubuntu pool (amd64, i386) (local copies: amd64, i386).
mkdir /tmp/xserver-xorg-core_1.11.4-really1.10
dpkg-deb -R xserver-xorg-core_1.10.4-1ubuntu5_*.deb /tmp/xserver-xorg-core_1.11.4-really1.10
cd /tmp/xserver-xorg-core_1.11.4-really1.10/DEBIAN/
sed 's/Version: 2:1.10.4-1ubuntu5/Version: 2:1.11.4-really1.10/; s/Provides: xorg-input-abi-12, xorg-video-abi-10/Provides: xorg-input-abi-12, xorg-video-abi-10, xorg-input-abi-13, xorg-video-abi-11/;' control > control.new
mv control.new control
cd /tmp
dpkg-deb --build xserver-xorg-core_1.11.4-really1.10
dpkg -i xserver-xorg-core_1.11.4-really1.10.deb
echo xserver-xorg-core hold | dpkg --set-selections
- Install the legacy driver of your choice.
- Enjoy.
Note that we've held the package at its present version. You will need to manually undo this (or just explicitly apt-get install xserver-xorg-core) if you want to upgrade later.

Not nouveau?
I thought nouveau had pretty good support for NV35.

Unfortunately, nouveau is still noticeably slower than the proprietary driver. Since I use this machine primarily to run CAD tools it's an issue.

Non e tanto un discorso di Fedora, quanto della configurazione del supporto di Xorg ai dispositivi estesi di input. Eventualmente occorrerebbe pungolare quelli del Linux Wacom Project per aggiungere un configuratore grafico per il driver.Come specificato all'inizio dell'articolo, basta connetterla e va, ma si perdono le funzioni estese. La procedura si segue solo e soltanto se c'e la necessita di sfruttare a fondo tutte le caratteristiche della tablet.In fondo fare due copiaincolla su un file di testo non e proprio devastante per la salute mentale, no?
