Few weeks ago, the desktop is upgraded to RHEL 7.3, then nautilus crashed when open it. Lucky, it is back to normal after clean its configuration.

linkirin@m91p:~$ sudo grep -e "nautilus[[0-9]+]: segfault .* in nautilus" /var/log/messages | tail -n 1
Dec 21 10:35:44 m91p kernel: nautilus[9525]: segfault at 18 ip 0000000000484592 sp 00007ffc9fc0e480 error 4 in nautilus[400000+147000]
linkirin@m91p:~$ rm -rf ~/.config/nautilus/

As title, hit this issue yesterday. There is a workaround by following steps:

linkirin@trusty:~$ sudo -i
root@trusty:~# cd /usr/lib/x86_64-linux-gnu/
root@trusty:/usr/lib/x86_64-linux-gnu# cp libxcb.so.1.1.0 libxcb.so.1.1.0code
root@trusty:/usr/lib/x86_64-linux-gnu# sed -i 's/BIG-REQUESTS/_IG-REQUESTS/' libxcb.so.1.1.0code
root@trusty:/usr/lib/x86_64-linux-gnu# ll libxcb.so*

VS Code not working on Ubuntu when connected using XRDP. · Issue #3451 · Microsoft/vscode · GitHub – https://github.com/Microsoft/vscode/issues/3451

Recently the 13″ MBPr got upgrade to macOS Sierra 10.12. If I want to let it can act as remote X11 server of Ubuntu 14.04 (my main working VM in intranet), I have to install a X.Org X Window System that runs on macOS.

XQuartz is for this purpose , see https://www.xquartz.org/.

Then the file /etc/ssh/sshd_conf needs to be modified, and the ssh service needs up. After ssh to Ubuntu, there are some error/warning messages:

Last login: Thu Oct  6 14:32:12 2016 from 10.0.0.1
manpath: can't set the locale; make sure $LC_* and $LANG are correct
linkirin@trusty:~$ gvim
Fontconfig warning: ignoring UTF-8: not a valid region tag

To fix these, add two more lines in the file:

linkirin@trusty:~$ cat /etc/default/locale
LANG="en_US.UTF-8"

linkirin@trusty:~$ cat /etc/default/locale
LANG="en_US.UTF-8"
LANGUAGE="en_US.UTF-8"
LC_ALL="en_US.UTF-8"

That makes my left hand has easier life…

I choose this:

sudo vi /etc/default/keyboard

then change

XKBOPTIONS="ctrl:nocaps"
