After trying a lot of distros on my 2011 Macbook pro (clean install) I decided on 2. Mint and Zorin 16. I like Zorin and have it installed. Works well, but I think that I have AMD Radeon 7400 problem. When I attach external monitor it will not mirrows - no icons on external mpnitor, Mint had that problem too. Any ideas?. Please, do not make me use terminal - I can barely see on this small screen
Hi @janusz,
You might want to try a third party driver
sudo add-apt-repository ppa:oibaf/graphics-drivers
sudo apt update && sudo apt -y upgrade
I copy and paste. I got long line of codes and at the end got message "segmentation fault"
Can you post a screenshot of the terminal ?
Polish a man?

I don't see the link what his issue has to do with your post.
Do not know how to. When I try the mirror I get message that my hardware can not support. In Mint did mirror but display on external monitor only. I have the dreadful AMD Radeon 7400 that is known for defects. I downloaded the driver from amd and is in .deb extension. Can I install it?. Thanks.
When the terminal is open hit alt + printscreen. The screenshot is saved in /home/pictures/

After long download I got at the end - Sub-process /usr/bin/dpkg returned an error code (1), Do I need to restart?
Try the first command, if that does not fix anything try the second one.
This command reconfigures packages that have been unpacked but not necessarily installed. An interruption at the wrong time can cause this database to become corrupt. This is especially helpful if you were running installation and the process was interrupted.
sudo dpkg --configure -a
This command can attempt to fix the dependencies in the package installer.
sudo apt-get install -f
Well, st happen. Zorin can not start. Got "opps something went wrong" I try to log out and shut down/restart but nothing work. Will have to wipe the drive and re-install. Lucky me, I have desktop working(win10). I will be back when I reinstall Zorin. Thanks
