[solved] broken gtk brosers - white screen

[keithspg]

I have built and installed multiple browsers that leverage webkit2gtk. All appear to run as they do not core dump or otherwise indicate any massive problems in the journal. The problem is that nothing is displayed. This is on an rpi 3B+ and B running armv7 or aarch64. Kernel is up to date as is the rest of the system. I am using matchbox-window-manager and have no problem using firefox or chromium, but am looking for a more lightweight solution. I launch MWM and a browser from xinit as I am setting it up in as a kiosk.

The list of tried browsers:
Midori - pacman -Sy midori
White screen. It looks like it is running. I get a title bar and can type stuff in. I can go to google.com, but nowhere else. Localhost, a server on the lan, My nas, nothing shows up though server name is in the title bar. Just a white page.
Errors in journal:

luakit pacman -Sy luakit
installs and also displays a white page. I can go to google.com but no further (cannot search anything). Also a white page for my NAS login or any of my local servers. It looks like it is running, just not displaying anything. The errors look like this:

Surf - I built this from source (AUR)
white screen but there are other errors in the log - will have to do more legwork on this as it looks like more than just not displaying anything, but it, too leverages webkit2gtk and also displays a white screen though it appears to run and be 'functional'.

Any ideas?

[keithspg]

There is something seriously wrong either with my setup or with webkit. I am fully willing to accept is it with my setup, but have no idea where to start. Like I posted, chromium and firefox work. No other browser I have tried displays anything other than a white page for any site except on google.com. Can anyone else confirm or deny that any other browser will work on armv7 or aarch64? Not just google.com, but any bog standard local host, your NAS, your router, (on the LAN) or news.google.com or somehtig other than wikipedia.

[keithspg]

digging in a bit more. I wonder if EGL is actually the problem.

So I started luakit and surf and epiphany at google.com (as root and as a user), no error. It displays the page. Then typed in 'news.google.com' as a search. It displays the page. Then selected 'Top Stories' and immediately get this error on the cli:
$this->bbcode_second_pass_code('', 'libEGL warning: DRI2: failed to authenticate
Could not create EGL sharing context.
Could not create EGL context.')
It is as if there is something going on that requires libEGL that just will not display. The journal (cli response) entries seem to indicate it is downloading page info, it is just not displaying anything. The graphics just freeze. Same for arcllinuxarm.org. I can display the main page, browse the forum. If I go to suckless.org and browse. Everything works until I click on something then it shows the DRI2 error and freezes. I have these relevant packages installed:
$this->bbcode_second_pass_code('', 'libva 2.10.0-1
libva-mesa-driver 20.3.4-3
libglvnd 1.3.2-1
libdrm 2.4.104-1
llvm-libs 11.1.0-1
llvm10-libs 10.0.1-4')

I note that when I set up raspiOS and go to raspi-config that it installs these packages when the display is set up:
$this->bbcode_second_pass_code('', 'Setting up libglapi-mesa:armhf (19.3.2-1~bpo10+1~rpt3) ...

Setting up libgl1-mesa-dri:armhf (19.3.2-1~bpo10+1~rpt3) ...')


I will see if I can duplicate this on raspiOS. Maybe it is a kernel 5.4 - 5.10 bug?

[robg]

I confirm that epiphany works fine (albeit painfully slowly) on my up-to-date 64bit ArchLinux ARM system, running on a RPI 4B 8G model with the linux-raspberrypi4 kernel. The warnings you posted do not appear. I am running lxqt and have the xf86-video-fbdev driver installed.

[keithspg]

Further digging. It cetainly looks as if EGL is part of the problem, somehow. When either luakit or surf (and associated packages) are installed and run on RaspiOS (fully up to date) it works. I do get one warning, but it does not stop the function of the browser. Something is up with Arch Arm or my install...

This is startx launching luakit on RaspiOS. The local address shown is a local server with php/js and served by nginx and it works 'just fine' as does google news. I get the 'Failed to authenticate' warning but it works.

Well, they are not broken, but xorg is somehow broken. Since @robg says it works, My guess is something it missing. It 'used to' work with these packages installed. As of 5.4.83 it worked. as of 5.10.x, all these prowsers are broken under xorg. they begin to display info and as long as DRI is not called, they work and continue to work. I can surf page to page. when the system calls DRI, though, it halts.
The reason I think the other browsers are not broken is that they do display under wayland. luakit and surfer (both webkitgtk browsers) work just fine if I launch weston and then the browser. I posted a different thread to figure out how to get that set up properly, but from weston, I can browse and never get the error and can actually render the pages that cause the freeze under xorg. I cannot get crhome nor surf to work under wayland/weston, but both luakit and surfer work fine. It seems as soon as I get this:
$this->bbcode_second_pass_code('', 'Mar 07 19:06:51 rune64 xinit[4931]: Could not create EGL sharing context.
Mar 07 19:06:51 rune64 xinit[4931]: Could not create EGL context.')
it freezes and goes no further. What packages may be missing? Mine is attached.

Are you using a DE? It may pull in some dependencies required by the browsers. Cf.:

I do not believe I am using a DE. We have a 'recipe' to build a basic image then add the packages we need(ed) to get our music player functional. We have had to adjust that recipe from time to time as things changed. the full x11/xorg system we are using is for a 'kiosk' browser setup to display our localhost nginx server of php/js pages. This 'recipe' worked fine until the kernel was updated.

With the 5.10.x kernel change we have noticed this 'white page' which seems to be tied to a DRI system call and we have also noted that we can no longer direct X11/xorg output to /dev/fb1. The output is always displayed on the HDMI output no matter what I set the "Option "fbdev" "/dev/fb1"" to. If it is /fb0, it goes to the hdmi attached screen. If it is fb1, it goes to the HDMI screen. I assumed this was a kernel regression that would be resolved in time but maybe it is related. Adafuit (the 3.5" spi tft display I am using) suggests reverting to an older kernel to get their overlay to work properly under X. This is their 'issue' https://github.com/adafruit/Raspberry-Pi-Installer-Scripts/issues/149 which suggests that their driver may be to blame on this xorg issue. If I set my command line to "fbcon=map:10" I get the login vt on the small screen. If I launch weston in kiosk mode from the cli of the small display with the fb backend, it displays the image on the small screen without issue, so the kernel seems to be OK. Could it be that xorg is not actually directing output to the fb?

I will look through your list and see if it matches mine. Could you do a 'pacman -Qqetn > pkglist.txt' so I can easily compare the package lists? Mine is attached.

Disclaimer: I am no expert and can only assist with basic trouble shooting. The output of `pacman -Qqetn` is attached.
Some thoughts: The issue is unlikely to lie with webkitgtk, as this is merely a web interface for Xorg, and thus any regressions would likely have manifested and been reported on other setups as well. This and this suggest that the error lies with Xorg drivers, pertaining to graphics memory allocation. Not sure how this relates to starting standalone applications via `startx`, but to isolate the issue, why don't you a) try running the browser from openbox and if that works b) try isolating which openbox dependencies allow you to run the application on its own.

I just installed openbox and it only installed these 2 packages:
$this->bbcode_second_pass_code('', 'Packages (2) imlib2-1.7.1-1 openbox-3.6.1-7')
I tried to launch it then it complained that I needed to install this:
$this->bbcode_second_pass_code('', 'Pacmages (2) python2-2.7.18-2 python2-pyxdg-0.26-8')
when I try to launch it on aarch64, I get a core dump. I'll have to spend some more time on it and try it on armv7...
