Linux- Grey screen

[skoff]

I noticed the entry in the FAQ explaining how to get rid of a grey screen. Unfortunately this doesn't work in the linux version. TVBrowser worked fine - absolutely excellent program - until I switched to Beryl. Now I get a grey screen. I can tell the information is there because the cursor changes shape and if I click I can get something, but there must be a way to fix this...?

Maybe it would help to change the LookAndFeel.
Do you have an other Java application to test, if it is also affected?

There is a Bug in Java 5 when using an XGL-Desktop like Beryl.

This should help:

export AWT_TOOLKIT=MToolkit

Or you could update to Java 6 (currently in Beta)

Thanks for the suggestions - I'll try fixing my java (It is 5.)), maybe I can switch from Sun to Blackdown or look for an ebuild for Java 6. I can't recall if I have any other java apps (I'm sure I must), so I'll report back if and when I fix this.

[bodo]

Don't use Blackdown. We don't support it.

Okay, I have installed java 6 and experimented with various settings and have achieved success as follows :-
Using these available Java Virtual Machines:

• [1] blackdown-jdk-1.4.2
  [2] sun-jdk-1.5
  [3] sun-jdk-1.6 system-vm

I found that it was necessary to follow the suggestion to 'export AWT_TOOLKIT=MToolkit'. After which
sun-jdk-1.5 and sun-jdk-1.6 both work, Blackdown doesn't work.
Thanks for the help.

I had the same problem with IntelliJ Idea. Changing java version didn't help but

export AWT_TOOLKIT=MToolkit

fixed it.

I've run into the same problem with the grey screen when running Compiz and was glad to find this thread. However, trying to set the AWT_TOOLKIT variable either in the console environment or by adding the equivalent Java-option (-D...) crashes my Java 6 VM (without caring whether I set it to MToolkit or XToolkit...):

The following dozens of lines of the generated log file will probably be of no interest except of the following two paragraphs:

The sys-info is missing my graphics card, ATI X1950Pro chipset with proprietary ubuntu drivers.

I am able to run TV-Browser in normal, non-XGL Gnome, but it also crashes with the same output when again trying to set either XToolkit or MToolkit.

Can anybody help? Might it be a 64bit problem I need to report somewhere (Ubuntu or Sun)? Thanks in advance.

Well, the problem seems to be the AMD64 distribution of Java6, as far as I could figure out.

Setting the default JRE to Java 1.5 via update-java-alternatives and using the above mentioned export, TV-Browser finally works.

Just thought I document this in case others have the same problem.

See you.

I got the same problem with amd64: it crashes the vm.
