Login GUI goes blank after install on Linux

 

Hey all,

I've thoroughly searched the forum and the web to find a solution to this problem to no avail.? I've installed TWS and IBGW on a fresh openSUSE Hyper-v installation which goes off without a hitch.? The programs launch fine and I can log in to my accounts.? Then after a few reboots, the GUI comes up but no buttons or text renders when I launch both programs.? I see where I can type something because my mouse changes, but no text is visible.? Uninstalling TWS and IBGW don't seem to fix it (it remains this way unless I do a clean install of the VM and start over).

Have any of you seen this?? It may be connected to my installation of the Eclipse CDT C++ IDE (I'm not sure but it's the only other Java-based program installed).? Any idea on what could cause the TWS/IBGW apps to launch blank like that (especially after it works once or twice)?

Cheers,


TJ

You can uninstall java library and reinstall it again instead of redoing the whole VM reinstall. This way you can pinpoint the culprit to be the java library settings issue (conflict with IDE).

If that doesn't fix the problem then its another library or OS issue which should be easily found but at least java is not the problem.

P.S. on Windows or Ubuntu I have not seen this happen so it could be an openSUSE issue.

I strongly suggest to isolate the trading environment through docker or (better) lxd/lxc-container.?

Have a look @ ?
In open suse, you might need to patch the UID-mappings.

Thanks for the suggestions.? After digging deep into the interwebs, I finally found the solution for anyone that's in the same boat.? Java and xrdp don't play well with color depths other (greater) than 24 bit.? Once I changed (reduced) the RDP setting to 24 bit and in xrdp.ini uncommented: xserverbpp=24 and changed: max_bpp=24, it all worked fine.

This was a doozy to figure out - hope nobody has the same pain going forward.
