Possibly we have to extend the usb mouse emulation for that." +https://listman.redhat.com/archives/vfio-users/2016-January/001596.html + +Unfortunately, I have never written a patch. I'm not even sure how I would apply a patch in Unraid, other than overwriting the bin file. So if this is ever fixed, I would simply hope that one day a new version of QEMU would get up-streamed into a new version of Unraid. + +So, here I am humbly asking for support. I don't know if it's as simple as just adding new definitions... and I have no idea what hex value to assign them. + +*edit* I also failed to get a temporary workaround to work by remapping the mouse buttons in the host VM using xmodmap using this command: + +`xmodmap -e "pointer = 1 12 3 4 5 6 7 8 9 10 11 2" &` +I tried saving `pointer = 1 12 3 4 5 6 7 8 9 10 11 2` in the host VM's root folder in .Xmodmap, but it did not propogate to guest VMs. The buttons were still their original mapping and running the xmod command had no effect. |
