Comment 78 for bug 1590590

BTW, some Dell Precision 7510 systems (possibly only Xeon systems?) have a hardware issue where the trackstick or the touchpad or both will periodically get "stuck" (stop responding briefly) when on A/C power, when switchable graphics is enabled, when there is significant 2D or 3D video activity being rendered on the Intel video card, and when the Alps device is being run by an Alps driver (either this Linux driver or the standard Windows driver) instead of being run in PS/2 compatibility mode.

However, Dell is not taking my complaints about this seriously, in part because they "have not received any other complaints about this issue".

If anyone else is encountering this issue, please contact me directly.
