Mouse pointer speed

[Bent Bracke]

Hi

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.

Cheers

I'll add that my pointer moves very slowly when I use my touchpad in
Turmvilla.

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

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.

Hi

I ran it without qemu like you suggested and it worked :-)

Thank you!
