I am getting this error when trying to run Monero Wallet from www.getmonero.org on my Ubuntu machine:

$ ./start-gui.sh

./monero-wallet-gui: error while loading shared libraries: libxcb-glx.so.0: cannot open shared object file: No such file or directory

I have downloaded the "monero-gui-v0.11.1.0" wallet. I tried this with both 32 and 64 bit version. I also installed all the required dependencies listed on https://github.com/monero-project/monero The Ubuntu system details are:

Description: Ubuntu 16.04.3 LTS

Linux pc 4.4.0-98-generic #121-Ubuntu SMP Tue Oct 10 14:24:03 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

Any help on this matter is appreciated.

Thank you.

  • try: ldd monero-wallet-gui | grep xcb then it if shows a filename, try: file INSERTTHATFILENAMEHERE

  • This is what I am getting: $ ldd monero-wallet-gui |grep xcb libxcb-glx.so.0 => not found libX11-xcb.so.1 => not found libxcb.so.1 => /usr/lib/i386-linux-gnu/libxcb.so.1 (0xf7730000) $ file /usr/lib/i386-linux-gnu/libxcb.so.1 /usr/lib/i386-linux-gnu/libxcb.so.1: symbolic link to libxcb.so.1.1.0 Commented Nov 8, 2017 at 8:23
  • You have 32 bit libs. Make sure you get a 32 bit monero-wallet-gui, and try again.

  • I checked again and get the same error with 32 bit too. The cli version although does not complain. How do I make the GUI work too? Thanks. Commented Nov 8, 2017 at 10:53
  • If you still get a libX11-xcb.so.1 not found, you need to install libX11-xcb.so (which I think ought to be installed already, but just in case). If it doesn't help, look for libX11-xcb.* on your disk, and run file on it.

I had the same error on a 64 bit system and could get rid of them via:

sudo apt install libxcb1:i386 libx11-xcb1:i386 libxcb1:i386 libxcb-glx0:i386 libfontconfig:i386 libx11-data:i386 libx11-xcb1:i386 libx11-6:i386 libxext6:i386

But afterwards still a segfault happens - seems that the monero wallet gui is not (yet?) compatible with 64 bit systems.

  • That's really fishy. Are you using a 32 bit binary somehow ?

  • yes, there does not exist a 64 bit binary for monero-wallet-gui at this time, I thought I could run the 32 bit binary on a 64 bit machine

  • I've been running on a 64 bit machine ages ago. If they don't supply a ready made binary for your particular arch, you can build it yourself, it works fine.
