Every now and then I search for new information on my Travelmate 4101WLMI laptop in case someone has had more luck getting all the components to work. I found a note on the German Ubuntu site suggesting that I boot with noapic (in /boot/grub/menu.1st) instead of pci=noacpi (which is itself better than acpi=off). I was so pleased to get working sound and built-in wired and wireless networking. It’s like a new laptop. This suggests that the boot hang is caused by APIC (
clock advanced interrupts system) rather than ACPI (power management).
So, I still don’t have
- the battery status in the GNOME panel. Apparently Acer Travelmate’s tend to have the wrong DSDT in the bios. I tried doing the recompile-the-DSDT thing without success. But it bothers me that the bios seems just fine for Windows. Apparently Windows uses the Smart Battery interface instead and the GNOME applet needs to support that. I clicked on the “upstream request” link in Ubuntu’s (awkward) Malone bug-tracker. I’m not sure if it did anything.
- the widescreen display resolution.
But I can live with that more or less.
