Acer Aspire 5732Z Black Screen on 11.04

[gambothell]

Hi All -

Is there a problem with Intel video cards and 11.04?

I have tried upgrading and using a live CD and live USB with the same results on this notebook. After upgrading or booting off live CD/USB, I see a black screen, not lit. I can here the login prompt and when I press [Enter] and type my password I hear the Ubuntu theme which means everything is up, but still have a black screen. If I try to go to a console, I am still working with a black screen. Yikes ... I know my Live CD is ok, because it boots fine on my Lenovo S10-3 netbook.

Upgraded from Ubuntu 10.10 32 bit, live CD is 11.04 32 bit. Hardware: Acer Aspire 5732Z with Intel Mobile 4 series chipset integrated graphics controller (rev 09) and 3Gb ram.

Very same problem with an Acer 5734z.

The grub menu displays, but after that it's a blank screen with no backlight. I can hear Ubuntu's startup sounds. Booting by selecting recovery mode is the same behaviour.

English:
If it is already installed:
In the grub you press B to edit the kernel line. Add at the end of the line acpi_osi = Linux kernel. Press the brightness up key while starting.
When you start editing the /etc/rc.local and add before exit 0:
setpci -s 00:02.0 F4.B=00
Edit /etc/default/grub, edit the line GRUB_CMDLINE_LINUX_DEFAULT:
GRUB_CMDLINE_LINUX_DEFAULT = "quiet splash acpi_osi = Linux"
Update grub with:
sudo update-grub2

If not installed:
Boot from the CD, purple screen is displayed press any key to enter startup options. In the boot options choose the language and press F6. Press ESC and write at the end of the line that says Startup Options:
acpi_osi = Linux
Press ENTER to start the LiveCD. When loading up press the brightness keys.

Sorry for my English, Google Translate.

Español:
Si ya esta instalado:

En el grub presiona la tecla B para editar la linea del kernel. Agregar en el final de la linea del kernel acpi_osi=Linux. Presionar la tecla de subir el brillo mientras que inicia.
Cuando inicie editar el /etc/rc.local y agregar antes del exit 0:
setpci -s 00:02.0 F4.B=00
Editar el /etc/default/grub, editar la linea GRUB_CMDLINE_LINUX_DEFAULT:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux"
Actualizar el grub con:
sudo update-grub2

Si no esta instalado:
Bootear desde el CD, cuando aparece la pantalla violeta presiona alguna tecla para acceder a las opciones de inicio. En las opciones de inicio elegir el idioma y apretar F6. Presionar ESC y escribir al final de la linea que dice Opciones de arranque:
acpi_osi=Linux
Presiona ENTER para iniciar el LiveCD. Cuando esta cargando presiona las teclas de subir el brillo.

No fix, but progress.

I have been able to get minimal graphics working in recovery mode: add "i915.broken=1" to the boot options.

I confirm that unknown47's post fixed it for me.

It's a backlight problem. The screen was not completely blank.

To reach a stage to be able to even edit the files mentioned by unkown47:

• At the grub loading screen, press "e" to edit the line. Add "i915.broken=1" to the boot options. Ctrl+x to boot.
• When you get into Ubuntu GUI, follow unknown 47's instructions for "If it is already installed:".

Thanks Unknown47. Your fix worked for me. I am writing this reply from the LiveCD 11.04. Thanks again Ubuntu community for the quick and professional support.

Yeah, thanks unknown47 - that worked for my Acer 5736Z too.

I still have a problem...

When I leave my laptop for a while it powers down the screen. I used to be able to just use the mouse and it turned the screen back on but not any more.

Anyone know how to fix this?

[Ephack]

Yes! It worked also on my Gateway NV78.
Many thanks for that!
