reassign #276 x2goserver found #276 4.0.1.6 thanks Hi Pascal,
reassigning this bug report to X2Go Server, not X2Go Client. On Mo 29 Jul 2013 15:30:03 CEST Pascal d'Hermilly wrote:
When I start qt/kde applications on the x2go server via the x2goclient, I get a grey application and a lot of error messages in the konsole. A workaround seems to be to change the graphicssystem to native instead of raster. However raster is the default in Kubuntu and it doesnt work when running things as root or through sudo.administrator@desktops-x2go:~$ sudo dolphin --graphicssystem raster X Error: BadDrawable (invalid Pixmap or Window parameter) 9 Major opcode: 62 (X_CopyArea) Resource id: 0x420007d X Error: BadDrawable (invalid Pixmap or Window parameter) 9 Major opcode: 62 (X_CopyArea) Resource id: 0x420007d X Error: BadDrawable (invalid Pixmap or Window parameter) 9 Major opcode: 62 (X_CopyArea) Resource id: 0x420007d X Error: BadDrawable (invalid Pixmap or Window parameter) 9 Major opcode: 62 (X_CopyArea) Resource id: 0x420007d X Error: BadPixmap (invalid Pixmap parameter) 4 Major opcode: 54 (X_FreePixmap) Resource id: 0x420007d X Error: BadShmSeg (invalid shared segment parameter) 128 Extension: 129 (MIT-SHM) Minor opcode: 2 (X_ShmDetach) Resource id: 0x420007c administrator@desktops-x2go:~$ sudo dolphin --graphicssystem native this works fine. Also gtk applications such as gimp works fine as root.This is quite a problem when you want to add/remove users and do other administrative things in KDE.
In x2goruncommand (the server-side script that is responsible for any application startup) sets this env var:
""" # disable rastering in >= KDE4.8 and Qt4.8 export QT_GRAPHICSSYSTEM=native """ That piece of info probably gets lost during the sudo call you perform. Maybe you want to play with /etc/sudoers... """ special line in sudo %admins ALL=(ALL) SETENV: /usr/bin/dolphin """ And then: sudo dolphin Does that work?
