Hi
Sorry about the lack of details.
It is possible that it's just too fast. I'm simply having difficulties clicking on anything because the mouse pointer moves around so quickly.
I'm running genode with qemu on Ubuntu on macbookpro via parallels.
It is a usb trackball which works fine on Ubuntu and OS X.
Kind regards Bent Bracke

Hello Bent,
In all the examples that come with Genode, the mouse pointer moves at what seems like an erratic speed. Is this a driver issue or something else?
I am afraid that your question is too unspecific to give you a good answer. Do you observe the erratic behavior on different machines and with different mouses? Are you referring to a PS/2 mouse (with the PS/2 driver) or a USB HID mouse (with the USB driver)? Or are you using a USB mouse with the PS/2 driver? In the latter case, the BIOS provides some rudimentary PS/2 emulation. It is really hard to diagnose the problem remotely.
That said, our PS/2 driver is indeed rather simple. It resets the mouse but does not attempt to set any specific parameters with respect to mouse speed or acceleration. You can have a look at repos/os/src/drivers/input/ps2/ to investigate.
If you observe the problem with the USB HID driver, this would surprise me because we are actually using the Linux USB driver on Genode. So the mouse should work just as well as on Linux.

so you run Genode inside a virtual machine (Qemu) inside a virtual machine (parallels)? Then of course the actual hardware, your usb trackball, does not play a role anymore. Using this kind of nested virtualization lead to different various problems for different people in the past.
A possible solution to circumvent the nesting of virtualization techniques would be to use your Ubuntu VM for building the Genode scenario, but instead of executing it within Qemu, you could boot the resulting ISO image again via parallels natively on your Mac OS in a second VM.

an 'export SDL_VIDEO_X11_DGAMOUSE=0' in the Linux VM might help a bit with this kind of problem.
