The only difference is the ‘name’ property of the ‘application’ tag. Comment information at the start of application part explained how to find applications’ […]

I’ve got some memory intensive works to do recently. So I managed to log in to lxde desktop again last night after repairing a long-pending black screen problem by just uninstalling Nvidia driver. However, I came up with a new problem this morning. After I set wallpaper on an external monitor, the desktop-preference program crashed by […]

Upgraded My Fedora to 26 today and found my VMplaye-12.5.7 can not be started on Fedora 26. So I reinstalled vmplayer with version 14.

I created a fedora VM on Lubuntu host this afternoon. When I reopen it tonight, I found the network icon on the top-right disappeared and the network function failed too. I tried some solutions on the forum but nothing helped. Therefore I stopped to do something else. When I came back to VMplayer and tried […]

I want the panel to stay in the back of other windows instead of hiding. There is such an option in the panel settings but seems not to be working. I managed to do that by editing /home/me/.config/openbox/lubuntu-rc.xml Add these lines just before the last line: <application name=”panel”> <skip_taskbar>yes</skip_taskbar> <layer>above</layer> </application> <application name=”panel” type=”dock”> <layer>below</layer> […]

Ubuntu 16.04:Chinese characters display improperly. Old methods don’t work. We need some new methods.

Ubuntu booted into emergency mode

I booted my system this morning and found it was forced into an emergency mode like this: I found an answer on askubuntu.com which talked about unmounting some device. This remind me of what I did last night. I configured my /etc/fstab file last night to add windows partitions’ infomations there, as well as a […]
