Compiz-Check -- no more "Desktop effects could not be enabled"

[brightJoker]

Solved my issue, whenever I plug into an external monitor from my laptop I have to turn off my laptop monitor and it saves my settings. Otherwise a simple # added to the begining of the external monitors resolution in xorg.conf fixes any compiz issues.

Hi guys,

Anyone who still has a problem and didn't solve it in the meantime, please post again. I will try my best to help you out.

I'm afraid you can't get Compiz running on that graphics chip.

If it's not on a notebook, consider buying an additional graphics card (Nvidia preferably).

Hi!!

I have the same problem and in fact I'm running Ubuntu 8.1 on an acer aspire one notebook. The problem is that until some days ago, before an updating, everything was working perfectly, and desktop effects too. Now, after updating, windows title bar disappears and desktop effects could not be enabled.

The output of compiz-check is:

Any suggestion?

Thanks in advance for your help!

Your intel chip is not set up correctly.
Post the output of

grep -v ^# /etc/X11/xorg.conf

and use the forum's [CODE] tag please (# button)

Hi again!

After all, I'm sorry but I'm new ubuntu user and I don't kwow the forum rules...
How should I use the forum's [code] tag? What doeas it means?


The output of the command you suggested me is:
Section "Monitor"
Identifier "Configured Monitor"
DisplaySize 195 113 # Added by GC as described in ubuntu acer aspire one guide
EndSection

Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
SubSection "Display"
Virtual 2384 768
EndSubSection
EndSection

Section "Device"
Identifier "Configured Video Device"
Option "NoDDC" # Added by GC as described in ubuntu acer aspire one guide
EndSection

Thank for your patience

Hi,

don't worry, just don't use the Quick Reply but click on "New Reply" (or "quote").
There will be a text editor then and in the control bar above the text field is a button that looks like this: #
That's responsible for the CODE tag and if you paste your text between the tags, it will be presented like this:

Section "Monitor"
	Identifier	"Configured Monitor"
	DisplaySize 195 113	# Added by GC as described in ubuntu acer aspire one guide
EndSection

Section "Screen"
	Identifier	"Default Screen"
	Monitor		"Configured Monitor"
	Device		"Configured Video Device"
	SubSection "Display"
		Virtual	2384 768
	EndSubSection
EndSection

Section "Device"
	Identifier	"Configured Video Device"
	Option "NoDDC"	# Added by GC as described in ubuntu acer aspire one guide
EndSection

Which is a) easier to read and b) usefull with long outputs.

Anyway, this section is causing your trouble, I guess:

	SubSection "Display"
		Virtual	2384 768
	EndSubSection

Remove it completely from the file, you will have to open it in a text editor like this:

gksu gedit /etc/X11/xorg.conf

Afterwards, you have to log out and back in again to see if it worked.

You were right! Now the compiz-check test went right and desktop effect are enabled.
The only thing it hurt me is that when I maximize windows (any type of windows) the title bar (including minimize and close keys) remain hided under top pannel. Please, have you any idea of why this pass? This is quite unconfortable and I don't knoow how to solve it.

Thanks again!
