History

#1

Updated by bill-auger over 4 years ago

it runs fine for me - maybe you may have a theme or some mouse cursors that are borked

normally i would suggest to try making a new user; but didnt you just install this yesterday?

#2

Updated by daniel-molina over 4 years ago

Yes, installed the system just some days ago.
I run it with gdb:

  • Status changed from unconfirmed to confirmed
  • Subject changed from lxappearance segfault to [lxappearance-gtk3]: segfault

i believe that this is confirmed now - the segfault is with 'lxappearance-gtk3', not 'lxappearance'

Updated by bill-auger about 3 years ago

for a work-around, until this is fixed, uninstall 'lxappearance-obconf-gtk3'

# pacman -R lxappearance-obconf-gtk3

the segfault goes away, after uninstalling 'lxappearance-obconf-gtk3'

when 'lxappearance-obconf-gtk3' is compiled with the PKGBUILD (same version), the backtrace is different

Updated by bill-auger about 3 years ago

for some reason, the arch BR was closed - i dont know why; because the bug is still present, and the package is still useless

libre/lxappearance-obconf-gtk3 0.2.3-.parabola1 fixes this for parabola; and 'lxappearance-obconf-gtk3' is added to the blacklist - i sent patches upstream and requested that the arch BR be re-opened - will leave this BR open for now

'lxappearance-obconf-gtk3' should be removed from the blacklist eventually, and the [libre] package deleted
