Bug Description
* Impact
The Ubuntu installer crashes on some machines (seems more often on hiDPI machines (QHD/UHD etc)).
* Test case
Try installing Ubuntu on an hidpi machine, it should complete installation instead of crashing.
* Regression potential
The fix in ubiquity touches the code handle uid drop/privilege, that can have unexpected side effects so we need proper/complete testing of the installer
----------
Update: Actually the crash occurs on slow-ish systems due to a race condition. It's not strictly only hi-DPI machines - that's just the most common place it is experienced.

WORKAROUND:
1. Boot into the live session.
2. Settings > Devices > Displays > Scale = 100%
3. Click Apply.
4. Proceed with installation: Click "Install Ubuntu 18.04 LTS".
---
Crashed in a VM in the middle of installation. The host is Bionic up to date.

This looks odd. We start with a 16x16 icon upscaled to 32x32 (scale=200%) but the pixbuf_x/y offset seems to be negative (memory underrun?). Is that a faulty attempt at rendering 32x32 from 16x16 input?

It has been brought to my attention by a community user, that the workaround (change scale from 200% to 100%) found in comment#14 works.
| Mario Limonciello (superm1) wrote : | #21 |
On an Dell XPS 9360 with a 3200x1800 display it also defaults to 200% and I reliably reproduce this bug with the 18.04 final image.
I can confirm setting the scaling to 100% in the live session resolved the crash.

Thanks @pjsingh5000. Your attachment shows the python stack ends at:
# There's still work to do (postinstall). Let's keep the user

Gtk.main()
Which agrees with what I see on screen when the bug occurs. It's the slideshow that never starts (or does, as a blank black/white image).
After that there is no debug info from comment #22. Although my attachment from comment #15 probably fills in the blanks: https:/
So it looks like the bug here is entirely in the C code.

Possibly relevant to permissions: The uid of this process changed from 'root' in 17.10 (where it works), to 'ubuntu' in 18.04 (where it doesn't work).
ubuntu 4468 17.8 1.2 502716 97352 tty1 Sl+ 08:17 0:01 /usr/bin/python3 /usr/lib/
In both cases the Xorg process is running as 'ubuntu'.

Getting closer. It's this failing in the Xorg process:

Unfortunately I can't tell what in shm_access is failing exactly because gdb skips straight from shm.c:314 back to the caller. So that suggests this code path, but I can't verify it:
static int
shm_access(
{
int uid, gid;
mode_t mask;
int uidset = 0, gidset = 0;
LocalClient
if (GetLocalClient
...
}
/* Otherwise, check everyone else */
mask = S_IROTH;
if (!readonly) {
mask |= S_IWOTH;
}
return (SHMPERM_MODE(perm) & mask) == mask ? 0 : -1;
}
So Xorg _should_ be returning an error, and it is. The problem seems to be that the client (python3 gtk_ui process) has a real uid=0 and effective uid=999. So that allows it to connect to Xorg (normally Xorg rejects root clients), but doesn't allow Xorg to check the client shm permissions. So Xorg rejects the client's attempt at XShmAttach.
How any of this relates to scale=200% and why it works at 100%, I'm not sure. We might need to review comment #15 in more detail.
| Daniel van Vugt (vanvugt) wrote : | #30 |
Given that XShmAttach can fail (you can google the reasons), I think maybe we need to handle that in ubiquity/cairo and fall back to an alternative rendering method.
I'm not so sure we should be treating XShmAttach failure as a bug.
| Daniel van Vugt (vanvugt) wrote : | #31 |
OK, I can now reproduce the problem at scale=100%. The trick is to slow down the installer with GDK_SYNCHRONIZE=1. So this is just a race condition, usually triggered by slower rendering of scale 200%, but can be triggered other ways.
| Daniel van Vugt (vanvugt) wrote : | #32 |
So it sounds like a race between Xorg and the ubiquity perms dropping which then breaks Xorg's ability to authenticate XShmAttach used in cairo.

Ubiquity also crashes inside a virtual machine (VirtualBox) running on a non-HiDPI host machine.
I have observed corrupted graphics in the "main area" of Ubiquity when this bug occurs. By "main area", I am referring to the rendered rectangular area in Ubiquity below the title bar and above the "Copying files..." progress bar.
The corruption looks like jagged diagonal lines or "snow". I have seen this on both actual hardware (HiDPI machine scaled at 200%) and in a virtual machine (non-HiDPI hardware scaled at 100%).

A patch to fix the crash is here:

If we fail to get cairo fixed for any reason, it's probably possible to do a workaround/fix in ubiquity. But I think there are now multiple reasons to fix cairo as first preference.

I tried the patch for /usr/lib/
Instead of corrupted graphics in the Ubiquity window, I saw a blank white area above the "Copying files..." progress bar.
After a few seconds, the Ubiquity slide show appeared as usual, and I did *not* get a crash.
I will also try this on actual hardware.

You will get the same behaviour using the cairo fix too:

An upload of ubiquity to bionic-proposed has been rejected from the upload queue for the following reason: "All looks good with the package itself, but sadly there seems to be some leftover .gladep file included with the changes. Could you reupload without it? Or, if it's needed, just mention that in the bug? Thank you!".
| Iain Lane (laney) wrote : | #42 |
Ah, I'm sorry, I didn't see that there had been a bionic upload for this since the vcs was untouched and there was nothing in the unapproved queue... I just uploaded ubiquity for this to *cosmic* - not bionic yet. If it gets approved it should be in the next day's dailies and hopefully someone can test those to verify it's good.

Removed the .gladep file; it seems to have crept in by error during the git migration (also in my cosmic upload) and uploaded bionic. Thanks and sorry cyphermox if this treads on your toes.

I can confirm that the package version from bionic-proposed solves the problem.
During an installation I used Dell 2715Q with settings as in the screenshot attached (single monitor mode, 200% scaling).
