I just did a wubi install of Ubuntu 11.10 ony my acer emachines E725. After I reboot, the display is too dark that I can only see the white backgrounds and my mouse (when it is in the middle of the screen where the wallpaper is a little brighter).

Before I did a wubi install I also tried live using usb.

Does anyone know how to deal with this. Should I go ahead and do a full install?

3) Select Test ubuntu and then install

4) Reboot

5) Press F6 and select nomodeset

6) Select Test ubuntu and then install

7) Open a terminal and:

$ sudo mount /dev/sda1 /media/ubuntu

$ sudo mount ‐‐bind /dev /media/ubuntu/dev

$ sudo mount ‐‐bind /proc /media/ubuntu/proc

$ sudo mount ‐‐bind /sys /media/ubuntu/sys

Edit line: GRUB_CMDLINE_LINUX="nomodeset"

Thank you. But I think I forgot to mention that I dual boot with windows (I did mention wubi). Anyway I kind of followed your tips and I get it to work. I followed point 1-3. Then after installing I edited /etc/default/grub as you mentioned then sudo update-grub. It works. – Francis Lalnunmawia Oct 22 '11 at 15:13
After much googling, i have found a (i think) better solution. With nomodeset, I could not change the screen resolution. I edited my /etc/default/grub with these lines GRUB_CMDLINE_LINUX_DEFAULT="quiet splash **acpi_osi=Linux**" GRUB_CMDLINE_LINUX="" instead of using nomodeset. But I have to increase the brightness (using brightness control in my laptop) to see the screen. – Francis Lalnunmawia Oct 22 '11 at 16:58

Thanks to Francis Lalnunmawia. Your solution is great. But if you

place /usr/bin/setpci -s 00:02.0 F4.B=80 in your /etc/rc.local file

so, your solution will be perfect.

Thanks. It really is perfect now. – Francis Lalnunmawia Jan 14 '12 at 14:04

The best solution is to upgrade your bios, I have the same computer here.

in windows flash it directly using the exe.

if you're in linux just install freedos (1.** mega) using unetbootin and put the bios files there then start system from freedos startup disk then CD to directory dos and run the .bat file.


ps : every new linux based OSes will work .

BIOS for e725 link (version 3.10)
