root [3] TBrowser b
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
Error in <RootX11ErrorHandler>: GLXBadContext (XID: 6291709, XREQ: 149)

Hi, Can you please provide additional information. On which machine? remote login? what version of ROOT? from where you got the installation? etc.

Hi,

This happen when i am using root from LXPLUS account , i am using my mac mashine , Version 5.34/36

thanks,

Mai

do you access lxplus with:

 ssh -Y lxplus

?

You will need to upgrade to the latest latest version of XQuartz. See topic X11 forwarding through ssh on lxplus

Hi,

Yes i am using ssh -X -Y

i will try to check the latest version of XQuartz

thanks,

Mai

Hi,

The version release is the latest (i think)
XQuartz 2.7.10_beta2 (xorg-server 1.18.3)

what should i do now?

thanks,

Mai

Did you run the command

defaults write org.macosforge.xquartz.X11 enable_iglx -bool true

and rebooted your Mac to activate the new Quartz?

Hi,

No, i mean my current XQuartz version is XQuartz 2.7.10_beta2 (xorg-server 1.18.3) , so i dont think i need to update it.

Also when i was trying to run my macro i got the below error, so i need to sort out where is the problem , is that related to ROOT , or XQuartz or my code itself.

sorry i am just a beginner so i need some details.

thanks,

Mai

Sorry, again did you run the command “defaults write org.macosforge.xquartz.X11 enable_iglx -bool true” in a terminal? and rebooted your Mac to activate the new Quartz?

The crash you are reporting is now different. The problem is in Monopole::SelectFirstSC(float&) and this is not a ROOT code.
