Hello all,
I use a Logitech diNovo Edge on my HTPC for several years and I'm very satisfied with it. But when I updated gentoo-sources yesterday, the touchpad stopped working on X.
The system saw it, and knew what it is (/dev/input/mouse0 and /dev/hidraw1 filled up when I touched the pad), X also saw it (it appeared into Xorg.0.log, without errors), but... the cursor didn't move at all.
Problem : the Logitech HID driver seemed to have disappeared :

But it mysteriously re-appeared when I selected "Lenovo / Thinkpad devices"...

In fact, selecting "Lenovo / Thinkpad devices" enables "LED Support" -> "LED Class Support" (CONFIG_LEDS_CLASS), which is necessary to enable "Logitech devices" (CONFIG_HID_LOGITECH). And so, selecting "LED Class Support" manually is sufficient to get the special Logitech HID driver available. I don't know why, but these different behaviours are a little disturbing.
If this can help... |
