I get something of an error regardless which JVM I use (I used java6, java5, and downloaded 1.4.2 directly from Sun). I'm not sure exactly how related this is, but I get other problems (I have a Java app whose Oracle JDBC driver can't even do a simple connect to a database). The JVM doesn't CRASH, but it does have a few xinerama references in the stack trace. I don't know if this is related to bug #174759 or not, but see attachment in case it rings any bells.

Status in Source Package "icedtea-java7" in Ubuntu: Won't Fix Status in Source Package "openjdk-6" in Ubuntu: Fix Released Status in Source Package "sun-java6" in Ubuntu: In Progress Bug description: Update: This bug has evolved a little, the summary for this bug now reflects the root cause of the problem, discovered later in the comments. It seems Java fullscreen exclusive mode is not supported when Xinerama is present in Xorg. In Gutsy it seems it is there on all installations (that I've tested) which means no Java fullscreen exclusive mode apps/games will run. Original Description: While testing a Java fullscreen mode application in Gutsy I have discovered that Java does not find the full list of supported display modes it only lists the current screen resolution even though the xrandr command lists all supported screen modes. Consequently it cannot use full screen exclusive mode in any other resolution than the current one in use. This is a regression as the problem does not occur in Feisty. I've tested this on 2 completely different machines first with Feisty and then with Gutsy. I've attached a sample Java program DisplayModeLister which outputs a list of supported screen modes. Here's it's output on Gutsy: 1: 1440 x 900 @ 0Hz -1bit Here's the xrandr command's output on Gutsy: Screen 0: minimum 320 x 200, current 1440 x 900, maximum 1440 x 1200 VGA-0 disconnected (normal left inverted right) LVDS connected 1440x900+0+0 (normal left inverted right) 0mm x 0mm 1440x900 59.9*+ 1280x800 60.0 1280x768 60.0 1024x768 60.0 800x600 60.3 640x480 59.9 S-video disconnected (normal left inverted right) DVI-0 disconnected (normal left inverted right) Here's DisplayModeLister's output on the same machine running Feisty: 1: 1440 x 900 @ 60Hz -1bit 2: 1024 x 768 @ 60Hz -1bit 3: 800 x 600 @ 60Hz -1bit 4: 640 x 480 @ 60Hz -1bit 5: 640 x 350 @ 60Hz -1bit 6: 640 x 400 @ 60Hz -1bit 7: 720 x 400 @ 60Hz -1bit 8: 1152 x 864 @ 60Hz -1bit 9: 832 x 624 @ 60Hz -1bit 10: 1280 x 768 @ 60Hz -1bit 11: 1280 x 800 @ 60Hz -1bit 12: 1152 x 768 @ 60Hz -1bit This result is the same in Java 5 and 6.
