Have four Sid machines here and ssh -X has worked fine on all of them for years. For the last several days I haven't been able to run graphical applications over ssh from any of these machines.
Error says "cannot open display" and if I ssh into the machine $DISPLAY is indeed blank but from a local console $DISPLAY correctly reads :0 export DISPLAY=ip.of.ssh.guest:0 doesn't work either although it does set the variable on the host machine. xhost + also gives the cannot open display error. ssh -vv -Y u...@ip.add.re.ss just gives "X11 forwarding request failed on channel 0" Since this happened on all four machines at once I'm pretty sure it's nothing I did - but I haven't been able to resolve it yet. Anybody else seeing this? Anybody got an idea how to resolve or which package to give a bug report? cheers -
