Since around 4 days ago X wont run, and my web searches show i'm hitting |
| 2 |
the same sorts of issues that arose when X moved away from running as root. |

In strace, i see; |
| 5 |
$ grep Permi startx11.out |
| 6 |
319 setpriority(PRIO_PROCESS, 320, -1) = -1 EACCES (Permission denied) |
| 7 |
320 openat(AT_FDCWD, "/dev/tty0", O_WRONLY) = -1 EACCES (Permission |
| 8 |
denied) |
| 9 |
320 openat(AT_FDCWD, "/proc/mtrr", O_WRONLY|O_CLOEXEC) = -1 EACCES |
| 10 |
(Permission denied) |
| 11 |
|
| 12 |
$ ls -l /dev/tty0 /proc/mtrr |
| 13 |
crw--w---- 1 root tty 4, 0 Oct 4 18:14 /dev/tty0 |
| 14 |
-rw-r--r-- 1 root root 0 Oct 4 18:14 /proc/mtrr |
| 15 |
|
| 16 |
$ grep libexec startx11.out |
| 17 |
320 faccessat(AT_FDCWD, "/usr/libexec/Xorg.wrap", X_OK) = 0 |
| 18 |
320 execve("/usr/libexec/Xorg.wrap", ["/usr/libexec/Xorg.wrap", |
| 19 |
"-nolisten", "tcp", ":0", "-auth", "/home/adam/.serverauth.303"], |
| 20 |
0x55b02e0cdc20 /* 38 vars */) = 0 |
| 21 |
|
| 22 |
$ ls -l /usr/libexec/Xorg.wrap |
| 23 |
-rws--x--x 1 root root 14392 Oct 2 19:19 /usr/libexec/Xorg.wrap |
| 24 |
|
| 25 |
Also from Xorg.0.log |
| 26 |
[ 176.550] (EE) systemd-logind: failed to get session: PID 320 does not |
| 27 |
belong to any known session |
| 28 |
|
| 29 |
I cant work out why there's an issue given the suid root on Xorg.wrap, so I |
| 30 |
rebuilt systemd and the X stuff, but no change. |
| 31 |
|
| 32 |
Any ideas? |
