Tried to run 18.04 in VM's on my work laptop and personal laptop and I'm just getting the same results - very slow responding OS no matter what. I've got guest additions installed as usual and ran updates. I've even given the machine 4 cores and 8GB ram on my home machine and it's still awful to use. I've googled around a bit and seems I'm not the only one but I can seem to find any fixes for it. Anyone else experienced this?
Do you have 3D acceleration enabled for the guest? 'cos that goes super-wrong with a Linux guest, I've found.
That is significantly better. Running linux mint 19 with 3D acc. still on and that is seemingly alright.
Yeah, I think it's heavily dependent on which desktop environment you use - I just turn it off as a matter of course, unless I know I'm going to need it for some reason.
I am a fan of VirtualBox, but I must admit I think VMWare's VMPlayer often works better. I still like VirtualBox since it is free and open source, and VM Ware is closed source with a free edition. If anything, I think VM Ware is a "it just works" solution with minimal options for user configuration, which is absolutely great until it doesn't "just work". Simply put, I would try running the virtual machine in WM Ware Player and see if it runs any faster, if it does you can then either keep using VM Ware or try to find the right settings to tweak in VirtualBox. Also, what are the specs of you laptop? Have you tried running the Ubuntu off of a USB flash drive to get it on bare metal to compare the speed? It might be the case that your laptop, for whatever reason, might always run Ubuntu at that speed.
Core specs of my laptop at home are: i5-8250U 16GB RAM 512GB NVMe PM961 It's no slouch, that's for sure. I might just dual boot or get rid of Windows altogether. I'm sure @Gareth Halfacree can guide me.
Everyone should ditch Windows for Linux! (Disclaimer: most people should not ditch Windows for Linux.)
Manjaro installed on the desktop, should be fun! I think I'm going to get a 1TB drive for the laptop and dual boot.
Because when I see a thread about this I think "I must have another go at that" rather than remember what a pain it was last time: I can confirm that more or less out of the box Ubuntu/Unity runs horribly here too. Mint/Xfce is indeed a lot better, but the best experience I found was with Lubuntu. It also had the simplest instruction to get guest additions working. This was with an i5-6400. VirtualBox and VMPlayer seemed to perform similarly. Unfortunately even Lubuntu couldn't playback 1080 video smoothly in VLC, which is kinda my benchmark for a day to day usable non-gaming system. It wasn't far off though, so any tips to improve video performance would be appreciated. EDIT: Allowing access to all 4 cores really helped. I guess I'm used to GPU accelerated video.
