    Re: [TX2 Touchscreen] Cursor jumps like hell

    After installing fglrx from Synaptic the touch screen is working much better, no ghost clicks. I must have missed a step with changing the drivers over, because now my system is acting as though there is no graphics acceleration. ATI control centre does not open, stating missing drivers. Visual effects can't be enabled. Also, the boot up and shut down screens are now a little rougher and the system doesn't shut down - just hangs on a black screen.

    Is it a conflicting driver issue? I couldn't find a radeon driver to remove...

    I'm not sure what that's indicating. The proprietary driver isn't installed correctly? Froms Synaptics? Don't you still get the ATI "flgrx" from Hardware Drivers.

    Anyway you may several ATI OSS drivers installed by default. Their names would be something like:
    xserver-xorg-video-ati
    xserver-xorg-video-radeon
    xserver-xorg-video-radeonhd

    I will try and remove the old radeon drivers later today. Thanks

    Removing the old drivers didn't do the job. Any other ideas?

    Is the fglrx driver loading (in lsmod)? If so, have you tried:
    Code:
    sudo aticonfig --initial
    You might also check to see what is showing up in /var/log/Xorg.0.log. It should provide some clue about what is happening.

    Thanks Ayuthia,

    That did the job.

    Code:
    uninitialised file found, configuring.
    Using /etc/X11/xorg.conf
    Saving back-up to /etc/X11/xorg.conf.original-0
    Hopefully all will go well from here!
