LXpanel flicker and Menu listings...

Of late I noticed these two issues.
1. Menu window (Application Graphics etc is there) suddenly becomes just a dot and no application can be selected.
A logout and log in solve this issue.
2. The LXpanel suddenly starts flickering and nothing can be selected and even Alt+F2 did not work. The solution was to
switch to another terminal, remove the panel setting file from /home/<user>/.config/lxpanel/LXDE/panels/ folder and switch back
to LXDE.
The icon set is Mashup. Any help to resolve this issue permanently.

Hi
What version of LXPanel are you using? I guess 0.3.999, right? 1) For the menu problem try
this fix. 2) Could you post the Terminal output when this happens? Have you tried to compile the latest svn?

you are right. The version is 0.3.999. My OS (distro) is Arch Linux and it is from the repo. The solution what I applied is somewhat the same but not thro' a script.

The flickering panel seems to be related to the netstat plugin. Best solution I know seems to be to compile the panel without it. Try this PKGBUILD:
Code: Select all

# Maintainer: Geoffroy Carrier <geoffroy.carrier@koon.fr>
pkgname=lxpanel
pkgver=0.3.999
pkgrel=1
pkgdesc="Panel of the LXDE Desktop"
arch=('i686' 'x86_64')

md5sums=('ba966c76811f2057198470567099d97d')
build() {
cd "$srcdir/$pkgname-$pkgver"
./configure --sysconfdir=/etc --prefix=/usr --with-plugins=netstatus,volume,volumealsa,cpu,deskno,batt,kbled,xkb,thermal || return 1

make DESTDIR="$pkgdir" install || return 1
}

I have the same issue with lxpanel-0.3.999 flickering when launching various applications such as IglooFTPpro. I've been able to track it back to the Taskbar (Windows List) segfaulting. I dont know if this will help anyone but my syslog shows Mar 30 01:12:32 localhost kernel: lxpanel[3348]: segfault at 18000ca ip b7a6a8ff sp bfc2ae10 error 4 in libgdk_pixbuf-2.0.so.0.1400.7[b7a60000+19000]

I had the same issue with lxpanel-svn (I'm using archlinux). I tried to solve it, but the best solution was to rebuild lxpanel package without the netstatus plugin. Instead netstatus plugin I used netstat plugin and it works great with my wlan interface (I have two interfaces, eth0 and wlan0, wlan0 is my default and primary interface for internet). I forgot to mentin, that panel flickering starts only with the wlan interface, and caused by netstatus plugin which probably is unstable.

The netstatus plugin should not be used. It is a known source of panel instability. One of the developers is rewriting it.

The first question
I have a solution in the wiki does not work
Here is my solution:
1. Сreate a file /usr/bin/fixmenu
#!/bin/sh
killall -s KILL lxpanel
file=`find ~/.cache/menus -name "*" -type f`
rm ${file}
lxpanel -p LXDE
2. Make it executable.
3. Сreate a file ~/.config/autostart/fixmenu.desktop
Code: Select all
[Desktop Entry]
Encoding=UTF-8
Type=Application
Name=fixmenu
GenericName=
Exec=/usr/bin/fixmenu
Terminal=false
Categories=System;

Sorry for bumping up old thread, but found cause of this problem (maybe it will be handy for someone).
In my case (debian testing/lxde 0.5.5.1) Lxpanel is placed on top.
Because of bug, I removed menu button from panel.
And right after it, I saw segfaults and flickering.
Put it back. and now I have both run dialog and no flickering.
