X.Org X Server 1.20.0 log

The X.Org X Server start up takes well over a second on an ASRock E350M1.

Debian Sid/unstable with Linux 4.18-rc4+ is used.

Looking at the log, there is half a second delay right below.

FWIW, this only takes a few milliseconds on my systems. You'd have to profile where the time is spent on your system, but it's more likely somewhere between glamor and Mesa / LLVM than in the kernel.

Thank you for testing that. Could you please list the details for one of these systems (hardware, Linux version, X server versions, …)?

Interesting. Is there a debug switch for the module glamoregl or do I need to use something like `perf` or `oprofile`?
Comment 3 Chris Wilson 2018-07-11 10:05:34 UTC
Fwiw, a few years ago, dlopen("libGL.so") took on the order of a second on a laptop HDD, which could be eliminated by prelinking. It might worth checking the exported symbol tables (objdump -T ?) to see if they are unnecessarily cumbersome.
Comment 4 Paul Menzel 2018-07-11 11:39:37 UTC
I tested this with an older Intel based Dell OptiPlex 7010, also with Debian Sid/unstable (Linux 4.17.3-1, and xserver-xorg-core 2:1.20.0-3) and an HDD – the other system has an SSD, the delay is with 1.8 seconds even bigger.

```

Looking at the messages though, *loalding* the module takes 200 ms. “Running it” takes long. 

Do you want me to change the component to *xorg*?

Comment 5 Paul Menzel 2018-07-12 17:34:51 UTC
Michel, Chris, I just noticed, that the delay is only there when starting the X.Org X server for the first time. Could you please make sure, that your systems are rebooted when trying this?

(During my tests I do not use a graphical login manager, and just log in on a terminal and execute `exec startx`.)

Output of `strace -tt -f startx`

I traced the startup with strace. Of course it’s slower that way, but there are several delays in there. Also, a lot of libraries are loaded seeming to take some time.

Here are the biggest “delays” I found.
