I was given an older laptop preinstalled with Zorin 12.4. I’m not super familiar with Linux, but I know some rough basics. Anyway, I spent a day updating the machine, as it hadn’t been used in over a year. I also spent the day trying to install Steam through Wine and managed to be only partially successful. (Steam loads, but it’s just a black window where my games library should be.) After that, I did a couple more updates and then set the machine aside for a couple days.
Today, I decided to use the laptop to watch a DVD. However, the movie wouldn’t play. I opened the Videos app, and it gave me an error message saying the DVD was unreadable. So instead, I decided to spend some time trying again to install Steam, this time giving up on Wine and installing the Linux version. However, the terminal commands would only start the install process and then it would fail. I right clicked the .deb file and hit “open with software install.” The software installer opened, but it just had a swirling loading icon for a really long time. I closed out and opened the software installer from the start menu, and when it loaded, every icon in it just had three horizontal dots instead of pictures. When I tried searching for apps, nothing would come up. I also have a red exclamation mark in the lower right corner that says “A problem occurred when checking for the updates.” I’m connected to the internet, as I’m posting this from said laptop, so I don’t think that’s the issue.
I had made a live disc for 15.2, so I decided to just install the newest version of Zorin. I put it in and loaded it up, but I wanted to give it a try first to see if it was compatible with this laptop. After connecting to the Wifi, I tried opening firefox, but it wouldn’t load. I then went to the software center to see if I could install anything. I tried two different apps, but both failed to install. I went to try a third app, but then the pictures all did the same thing that happened after I tried installing Steam through the software installer in the 12.4 version: all the pictures turned into three horizontal dots in a row. I tried opening firefox again, but it still wouldn’t come up. When I tried restarting, though, it said that two instances of Firefox were not responding.
I restarted and got back to 12.4. I then decided to try to take a screenshot of the weird dots. However, before I could press the screenshot button, the window vanished. I now can’t get it open again, even when I restart the computer.
So, right now I’m kinda just like… what do I do? I know from past experience that an OS on a live disc can perform much differently than it does after installing, but I’m not sure if it’s worth the risk of installing it when I was getting similar issues on it that I’m already having on the current version of Zorin I’m using. I currently have the core version installed, and the version of 15.2 I have is also core. Should I be using lite instead? It’s not a super old computer, but it came with Windows 7 preinstalled originally, so I guess it’s kinda getting up there in computer years…?
Idk. Any advice would be much welcome. Thanks!
