14.4.1. X11 Buildroot mouse not moving
TODO 9076c1d9bcc13b6efdb8ef502274f846d8d4e6a1 I’m 100% sure that it was working before, but I didn’t run it forever, and it stopped working at some point. Needs bisection, on whatever commit last touched x11 stuff.
-show-cursor did not help, I just get to see the host cursor, but the guest cursor still does not move.
Doing:
watch -n 1 grep i8042 /proc/interrupts
shows that interrupts do happen when mouse and keyboard presses are done, so I expect that it is some wrong either with:
-
QEMU. Same behaviour if I try the host’s QEMU 2.10.1 however.
-
X11 configuration. We do have
BR2_PACKAGE_XDRIVER_XF86_INPUT_MOUSE=y.
/var/log/Xorg.0.log contains the following interesting lines:
[ 27.549] (II) LoadModule: "mouse" [ 27.549] (II) Loading /usr/lib/xorg/modules/input/mouse_drv.so [ 27.590] (EE) <default pointer>: Cannot find which device to use. [ 27.590] (EE) <default pointer>: cannot open input device [ 27.590] (EE) PreInit returned 2 for "<default pointer>" [ 27.590] (II) UnloadModule: "mouse"
The file /dev/inputs/mice does not exist.
Note that our current link:kernel_confi_fragment sets:
# CONFIG_INPUT_MOUSE is not set # CONFIG_INPUT_MOUSEDEV_PSAUX is not set
for gem5, so you might want to remove those lines to debug this.
