Something very curios happens with my PC and Linux. It can run fine for hours on end but if run a Java app it turns the screen off. In the end I have to turn the power off and cold boot. I remember somebody mentioning a similar problem with a duff BIOS and ACPI but why Java? It doesn't matter what distro I run it seems to have a problem with Java 1.5 and later.
To be honest it's a machine specific problem. The same software runs fine on other boxes. I just wondered what the JRE did to cause trigger the fault.Originally Posted by Geoff
@ITWombat: Have you tried the obvious - graphics card drivers, memory and hard disk diagnostics, etc.?
I don't think it's the memory because the machine POSTs OK and all other software works fine. It's not hard disk related because it happens with Live CD distrosOriginally Posted by Ric_
As graphic card drivers, the funny thing is it happens with the more update distros which should have more recent drivers.
I'm not really not going to spend any on fixing the box. I just though there might be a workaround I could use when I need to run Java software. I tried switching off ACPI as a boot option but that didn't work,
I've had all sorts of interesting errors that were traced back to bad ram. I seriously suggest you run memtest86 on the machine for awhile just to be sure.I don't think it's the memory because the machine POSTs OK and all other software works fine.
