It’s the 64 bit capable CPUs running 32 bit that have some vulnerabilities. The vulnerabilities that are fixed make my baytrail a bit sluggish compared to a year ago. It’s tempting to run an old [EOL] kernel.

#82

New LightDM which should fix the segfaults. If it does that should mean a new x32-stable snap should be possible!

#83

Finally, our prayer has been heard :joy: , I can’t wait for the server to get updated and try this patch to see if the issue has been fixed. Just few 7 lines of code that makes all the difference, Memory infinity and beyond :rocket: .


#84

Yeah! I can log out now!! Why would I want to though??


#85

Cinnamon x32 is working with systemd 240. I just finished the GUI update (enabled downgrade in pamac, but it wasn’t used.) Linux-4.19.16 is working too. Seems this update was smoother than the 64 bit testing. :face_with_raised_eyebrow:


#86

I don’t know about that - for the past month some people haven’t had a properly-working LightDM. :wink:


#87

Well, my Cinnamon was installed quite a while ago. Just looking in /etc I see several .pacnew’s including one for lightdm-gtk-greeter.conf.pacnew. Looking at it though, all I see are comments and a single section header. My own .conf has several parameters set and there are differences in the parameter names list.


#88

Here is my old lightdm-gtk-greeter.conf (intel Z3775, i915 integrated graphics) that works, default values - auto-login. Cinnamon over XFCE x32.

[greeter]
background = /usr/share/backgrounds/breath.png
font-name = Cantarell 10
xft-antialias = true
icon-theme-name = Vertex-Maia
screensaver-timeout = 60
theme-name = Vertex-Maia
cursor-theme-name = xcursor-breeze
show-clock = false
default-user-image = #avatar-default
xft-hintstyle = hintfull
position = 50%,center 50%,center
clock-format =
panel-position = bottom
indicators = ~host;~spacer;~clock;~spacer;~language;~session;~a11y;~power

I was not able to get Cinnamon running on a recent 64 bit XFCE 18.02 install on another partition. Cinnamon was irrelevant to exploring the old boot logo hang with 4.19, (which worked in 64 bit) so I re-used the partition for another distro. Nope, different distro, but it was a login failure. I used the community Manjaro Cinnamon ISO as a base to make a bootable UEFI32 ISO.


#89

And after many days I have a successful Firefox build:

#90

…Must mean a newer version coming REAL soon!!!


#91

Yes; I think that was the last remaining major hurdle to a new x32-stable release.


Can I ask any testers to please check in with any remaining issues.

Please update your votes on the “is it ready” poll in the OP.


#92

Its gonna be a big one … wonder how many stable users will backup first?


#93

My Lightdm works again - thank you.


#94

YAAAY :smile: Finally, LightDM is fixed. Now I can see my beautiful :sparkles: 32-bit Desktop in all its glory :joy: .


#95

I still have issue with firefox while opening it. I have to open Task Manager and kill one of the firefox process, the one with smaller memory, after killing that process, it finally launches. Anyone have this issue?? :thinking:


#96

Unfortunately problem with lightdm persists. Just made latest upgrade. LightDM 1:1.28.0-1.3

If i have missed something ?

The second weird problem appeared. When to press Alt Gr + any other button, whole graphical environment freezes. Mouse cursor moves, CAPS LOCK works, but no any other response. Only Ctrl+Alt+Backspace fixes it.


#97

Hmmm… :thinking:, Do you have Plymouth installed?? Could that be the reason or something else, it is strange I used get same coredump error like yours but after recent patch to lightdm, it got fixed.


#98

I’m getting this dumping…anybody else?
