I connect to an Xvfb based x server from C++ using xcb_connect. However, occasionally the last xcb_connect call fails:
xcb_connect: error code: 0 Display: :5 displayname: (null) screenp: 0 xcb_connect: error code: 0 Display: :5 displayname: (null) screenp: -943246996 xcb_connect: error code: 0 Display: :5 displayname: (null) screenp: -943246996 xcb_connect: error code: 1 Display: :5 displayname: (null) screenp: -943246996 The last one fails with a XCB_CONN_ERROR. Anyone has an idea how to debug this? Xvfb never produces messages be it on stdout ot stderr. Regards
