[Techtalk] Spastic Mouse After Using Virtual Console

[Dom Incollingo]

Hello,

I am using a PS/2 scroll mouse with SuSE 8.1.  The mouse works perfectly, except when I open a virtual console (ctrl-alt-F1, for example) and then return to my graphical session (ctrl-alt-F7). Upon return to my graphical session, the cursor does not work. Any cursor movement seems to be interpreted as clicks rather than pointer movement. Even if I don't try to move the mouse at all, programs start launching automatically, as if the mouse were clicking spastically on various icons.

If I toggle back through two or three virtual consoles (ctrl-alt-F1, ctrl-alt-F2, for example) and then return to the graphical session (ctrl-alt-F7), the mouse works normally again.

Here's what I've tried so far to resolve this problem:

- Checked /var/log/XFree86.0.log to verify that XWindows is using /etc/X11/XF86Config (shown at the end of this note)

- Verified that XF86Config contains the ServerFlag "AllowMouseOpenFail".

- Modified the mouse section of XF86Config to use device "/dev/mouse" rather than "/dev/psaux". No improvement.

- Added /usr/sbin/sysp -s mouse > /dev/null to /etc/init.d/boot.local. No improvement.

- Disabled 3D acceleration. No improvement.

- Checked /var/log/warn and /var/log/faillog to see if the problem was reported. Did not find any pertinent messages.

- Verified that gpm is not running by executing 'ps axw | grep gpm' in the shell. This command did not return any output.

- Tried starting gpm. No improvement. (Didn't think this would help, but thought it was worth a try.)

- Made the following change to /boot/grub/menu.lst as per the SuSE Support help:
  Changed the line:

   kernel (hd0,1)/boot/vmlinuz root=/dev/hda2  hdc=ide-scsi  vga=791

  to:

   kernel (hd0,1)/boot/vmlinuz root=/dev/hda2 acpi=off hdc=ide-scsi vga=791

    This did not help.

- Added the following line to /etc/X11/XF86Config as per the SuSE Support help:

     Option        "SW_cursor"

   below VendorName "NVidia" of the Section "Device".
    
   This change prevented the mouse from working at all, so I had to remove it.

- Searched newsgroups in google. This problem was reported before, but I did not find any solution.

Has anyone had this problem and found a way to resolve it?  Thanks very much for your help!
