Almost everything works, including simple and double clicks, and scrolling. Dragging is still broken. I must note I'm now using a synaptic Xinput driver, as suggested. The system seems much more stable in regard to suspension/resuming. The USB subsystem has kept working the first time I suspended and everything came back perfect. The second one in a row, the USB subsystem was halted, but doing a "modprobe -r uhci_hcd; modprobe uhci_hcd" made my USB periferals (keyboard and mouse) work again. As for the battery charging pattern, I can't say anything definitive, but it looks good ATM. No more "Ramdom Nasty Things(tm)", the clock works ok and there are no issues with proccess spawning. 9/10? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
