I made a guess at the applicable package; apologies if I guessed wrong.
I could have guessed grub-common as well.
Just installed Xubuntu Saucy Beta-2 today alongside of another OS (Linux Mint
15 Mate).
Mini-ITX motherboard home-build: Intel D2550MUD2 (Intel Atom 2550 GMA3650 i.e.
Cedartrail).
The motherboard BIOS has not been updated since I purchased the motherboard.
In general, I have no complaints about quality and speed of Xubuntu Saucy
components that were automatically selected:
* Kernel graphics module: gma500_gfx.
* Xorg video driver: Modesetting.
One oddity that I do not understand: in the Settings Manager > Hardware >
Display application, it shows me two displays:
* Acer Technologies 22" (correct)
* "Laptop" (This is fictitious. How could have it been "detected"???)
By default, both displays have "Use this output" checked i.e. enabled.
When "Laptop" is enabled, it overlays part of the actual Acer display.
In the default situation, when I request a reboot function from the
Panel-0 Session Menu reboot item, click on the Panel-0 reboot Action
Button, or enter `sudo reboot` from a terminal window, rebooting
proceeds consistently as expected.
However, the "Laptop" display is a nuisance in these circumstances as it
is not useful as it blocks part of the Acer display. I thought this
would be an easy fix: Uncheck "Use this output" for the "Laptop" display
and accept the changes. However, when I subsequently request a reboot
from one of the actions described above, the shutdown aspect of the
reboot process seems to hang up somewhere because the motherboard BIOS
never restarts.
To summarize,
* "Laptop" enabled: Reboot always proceeds.
* "Laptop" disabled: Reboot always hangs.
The attached extra debug information will be automatically collected in
the "Laptop" disabled case.
I would appreciate it if someone with a more mainstream motherboard than mine
and only one physical monitor would do the following and report back:
1. After installation, how many displays are presented?
2. If there are two, please try what I did above.
Thank you.
If it turns out that this is just another Intel "feature" in Cedar Trail
(one of the abandoned Intel motherboard product), I'll have to resigning
myself to cursing a lot [(-:], installing Windoze 7 on this rig, and
selling it on eBay! )-:
