Control: found -1 2:21.1.4-3 * Jakub Wilk <jwilk@jwilk.net>, 2022-02-11 23:17:
the X server no longer works for me: I get only blank screen. Worse, the blankness remains even after I zap the server.
I've bisected this; the first bad commit is 4e670f1281ad75c5 ("modesetting: Add CTM RandR property").
Reverting this commit (on top of 2:21.1.4-3) fixes the bug for me. -- Jakub Wilk
