I've looked at the Xorg.0.log you attached and would advice you to first fix the resolution of your screen (the tablet in this case). The 800x600 you get is exactly half of the Cintiq resolution (UXGA 1,600 x 1,200 pixel). Perhaps, only speculation, this is why a 1 cm move of the stylus moves the pointer an inch... At least that wold explain it if it's the mousedev still "owning" the stylus. If you do a "make menuconfig" of the kernel and look at Device Drivers --> Input device support --> Horizontal screen resolution and Vertical screen resolution, those are the values the "Mouse interface" (the menu option a bit above) follows if you, as the help text says: --quote-- If you're using a digitizer, or a graphic tablet, and want to use it as a mouse then the mousedev driver needs to know the X window screen resolution you are using to correctly scale the data. If you're not using a digitizer, this value is ignored. --unquote-- Anyway, first fix X. And to do that takes some knowledge if, as your log shows, the driver can't get things right. You've specified the "nv" driver to handle a "Quadro FX 3000"... That's like putting a donkey in front of a race car, but that's your choise... Even using the "nvidia" driver as I do, it takes some tinkering to get the most out of modern screens. For this laptop I need to specify: HorizSync 28.0 - 96.0 VertRefresh 50.0 - 86.0 To "unlock" higher modes than the standard vesa. Then I must set a modeline: Modeline "1280x800" 101.92 1280 1312 1696 1728 800 816 825 841 Search the web for something appropriate for your 1600x1200. And with the nvidia driver I do 'Option "IgnoreEDID" "1"' because it doesn't work with this laptop (and NVIDIA-Linux-x86_64-1.0-8178) Then make sure the DPI is uniform... With such a nice tablet you'd want it as crisp looking as possible. If the DPI is scewed, there will be blur. I have the following option set: # Size gotten from http://www.prismo.ch/comparisons/notebook.php # Size Diagonal Width Height Ratio Area Density at 1280x800 # 15.4" 39.12cm 33.17 20.73 8:5 688 cm2 98 pixels per inch # I've set the width to 331 instead of 332 to get a uniform # "DPI set to (98, 98)". Otherwise it would be (97, 98). DisplaySize 331 207 # Aspect ratio 1.6:1 (8:5) According to the wacom site you have "Display Area 432 mm x 324 mm" Also, with nvidia make sure to set 'Option "RenderAccel" "true"' The speedup is incredible. The "nv" driver from X is a bastard 2D-driver only, provided by nvidia once upon a time, and written in an obfuscated way to hide "secrets". Don't 'Load "dri"'. It's not used by your 2D-only "nv" driver, and not used by the nvidia driver either. Load as little as possible explicitly. If something needs something, it will be loaded automatically. But _do_ load the glx (as you already do). After you've gotten a nice screen, then examine the wacom situation. Run the tests specified on the web-pages (wacdump, xidump if I remember correctly) so that you know the wacom driver is in charge of the stylus, and not the kernel/X mouse driver. And don't "over-do" your configuration. The only extra parametres I've set for wacom is: Option "KeepShape" "on" # Adjust for my widescreen. So a drawn circle shows as a circle and not an elipse. I loose a bit of tablet area at the bottom because this is no "widescreen" tablet. Ok, I wish you luck.
