Dear experts,
Since 2 days ago I cannot open any graph interface in ROOT at CERN lxplus. When I try to draw something or do “TBrowser b”, it crashes and displays error messages without stopping, as pasted below. But I can still open other graphs, e.g. “display XXX.png” without problem. Any help will be greatly appreciated. Thank you in advance!
Best,
Jian
