Bug#556: hp-toolbox segfaults when started in x2go MATE session
by erik.devriendt＠telenet.be 15 May '15

Package: nx-libs Version: 3.5.0.27 Distribution: Linux Mint 17 64-bit. hp-toolbox segfaults when started in a x2go MATE session. hp-toolbox is a python script, part of the hplip-gui package in Linux Mint 17. After unsetting the LD_LIBRARY_PATH environment variable, hp-toolbox starts without segfaulting. (hp-toolbox started in a shell in a terminal window).

Control: close -1 Closing #341 because other people seem to be able to install nxproxy just fine.

Bug#637: nx-libs improvements
by Michael DePaulo 15 May '15

15 May '15

Hi Andre. I know it's been a while since you replied to this bug. However, the X2Go project and the Arctica Project have started doing major code cleanups to nx-libs on the new 3.6.x branch. Many of those code cleanups are big because they involve making nx-libs using the system version of X11-related libraries rather than nx-libs bundling its own (horribly outdated) version of those libraries. Those changes will improve compatibility with some X11 apps, but not Qt5 apps. After those code … [View More]
