Hi, Arthur Huillet,
I meet a problem seems very strange. Can you help me to check? I really
don't know how to solve it. (by the way, is there any xpra user forum to
discuss how to use and solve the problems of xpra?).
*I installed nvidia driver on Fedora 17. I think the installation is
successful since Display:0 can work well and glxinfo of display :0 is as
follows:*
name of display: :0
display: :0 screen: 0
