Hi @utopiabound

AFAICT, this issue should be fixed now.

utopiabound · 2023-07-13T14:03:30Z

This is not fixed in 1.0.7:
fvwm.Pager.txt

@ThomasAdam
Can this be re-opened, since the stack trace is almost identical, or should I open a new ticket?

Done. Can you also provide me with a means of reproducing this, please?

@utopiabound

Done. Can you also provide me with a means of reproducing this, please?

I don't have a reproducer yet, but I'll try to keep an eye on it to figure it out. Do you need any info from the core file?

Thanks, @utopiabound

What's the output from xrandr, please?

Module boundaries into libs/ in fvwm can sometimes be problematic. As such, calling into X11 libraries with an assumed display variable which is initialised from fvwm, but not from modules, can sometimes mean this isn't guaranteed to work. Implement these X calls local to FvwmPager instead. Fixes #833

ThomasAdam · 2023-08-29T20:49:37Z

Hey @utopiabound

Please can you give ta/gh-883 a try when you get a moment? It's rebased against main and I think fixes this problem.

In looking at your backtraces more closely, I think this is down to modules calling into library code which might not have a fully initialised environment. Easier to move the X11 calls to FvwmPager in this case.

Sorry, I missed this. I've upgraded to 1.0.8 and I still have a crash:

The issues is that on line 478 m_width is 0, this is caused by *mon being:

{
    name = 0x1cbceb0 "DisplayPort-0", 
    is_primary = 0,
    output = 84,
    win_count = 0,
    wants_refresh = 0,
    is_disabled = 0,
    is_current = 1,
    x = 0,
    y = 0, 
    w = 3440,
    h = 1440,
    virtual_scr = {
        VxMax = 12000,
        VyMax = 2880,
        Vx = 12000,
        Vy = 0,
        VxPages = 0,
        VyPages = 0,
        VWidth = 0,
        VHeight = 0,
        CurrentDesk = 0, 
        MyDisplayWidth = 6000,
        MyDisplayHeight = 1440
    },
    entry = {tqe_next = 0x1cc5c80, tqe_prev = 0x1bf7aa0}
}

A clue might be that *fp_monitor_q.tqh_first is:

(gdb) print *fp_monitor_q.tqh_first
$20 = {name = 0x1bf72a0 "DisplayPort-0", is_primary = 0, output = 84, win_count = 0, wants_refresh = 0, is_disabled = 0, is_current = 0, x = 0, y = 0, 
  w = 3440, h = 1440, virtual_scr = {VxMax = 12000, VyMax = 2880, Vx = 6000, Vy = 0, VxPages = 3, VyPages = 3, VWidth = 18000, VHeight = 4320, 
    CurrentDesk = 0, MyDisplayWidth = 6000, MyDisplayHeight = 1440}, entry = {tqe_next = 0x1bf7a40, tqe_prev = 0x44b560 <fp_monitor_q>}}

That has the same name as the "current" screen, but has the correct virtual_scr.

It seems to be growing each time the monitor disconnects and reconnects.

Do you need anything else?

ThomasAdam · 2023-12-14T18:04:13Z

Hi @utopiabound

Apologies this issues has bounced around a bit. I should be in a position to fix this, so I will take a look.

If I need any additional information from you, I'll let you know.

ThomasAdam · 2023-12-14T18:07:39Z

The fact the list of monitors grows like that tells me where I need to look -- and FvwmPager has always been an oddity in dealing with this. I'll dig further...

ThomasAdam · 2024-03-17T17:45:20Z

Hi @utopiabound

Please can you try the main branch? I've completely simplified how FvwmPager receives and monitors its list of screens, so I'm hoping this is fixed now.

FInger's crossed!

I have not had a recurrence of this issue since updating. I believe this is fixed.

@utopiabound Can you test #972, we have done a lot of changes to the pager and improving both per-monitor and dynamic changing of monitor support.
