I have an Acer 5334 and had the same problems. Since then I just downgraded to 10.04 since I like that one more than the latter 11.10. But to help you rather than just saying downgrade read my to do file I created for this very problem.
The Intel GMA 4500M video card does not play well with later distros (That's at least what video card I have with this Acer Aspire). The back-light does not turn on properly so prepare to have a flash light next to you. To fix this you'll have to open the terminal and type this:
Code:
sudo setpci -s 00:02.0 F4.B=00
I recommend if you want to install the later versions of ubuntu based OS's that you run the live cd first open terminal and enter the above statement then install. Keep in mind that this is a temp fix at the moment. I will share how to further fix permanently. Once you have installed and rebooted. Re-type
Code:
sudo setpci -s 00:02.0 F4.B=00
in the terminal so you can see without your trusty flash light/cellphone led flash light. Now that you can see properly type in the terminal
Code:
gedit ./etc/pm/sleep.d/9_lcd_backlight.sh
(if not gedit then any other text editor) this will create the file 9_lcd_backlight.sh. 9 is the priority you can put any number through 99 I believe, but it doesn't matter in this case. Paste the following below into the file you created, this will make sure when you boot from suspend or hibernate the back-light will be activated.
Code:
#!/bin/bash
case $1 in
thaw)
setpci -s 00:02.0 F4.B=0
echo "oh, suspend to disk is over, we are resuming..."
;;
resume)
setpci -s 00:02.0 F4.B=0
echo "hey, the suspend to RAM seems to be over..."
;;
*) echo "here we GO!."
;;
esac
With the bash file in place you now need to make the file executable. Make sure you are in the directory ./etc/pm/sleep.d/ and type this in the terminal:
Code:
chmod +x 9_lcd_backlight.sh
Once the bash file is now executable lets make sure the back-light turns on when you boot up. Input the next 2 lines in ./etc/rc.local file at the bottom line. So type in the terminal:
Code:
gedit ./etc/rc.local
This will open rc.local file. Now at the bottom make sure it looks like below and save.
Code:
sudo setpci -s 00:02.0 F4.B=00
exit 0
You should be fine, reboot and check it out.
