I believe this slowness has to do with me installing some stuff. But since i new to linux i have no idea how to see and remove what i have been installed. I tried Ubuntu Software center but everything i installed isn’t there. Also to boot it takes hell of time than before. Everything start happening after few updates. But i cannot be sure of which update.
So can someone please help me resolve this. I just need to go back to my normal speed. I can’t and i don’t have time to reinstall ubuntu MATE again.
If you knew what packages are the culprit, Synaptic is a package manager great for managing them.
To see a recent history of what you had installed, take a look at this command:
grep "\ install\ " /var/log/dpkg.log
I'm not sure why boot time would be affected, unless you had installed a service... this isn't Windows after all.
This command will output the services and how long it takes for them to start:
systemd-analyze blame
My advice next time is to create a perfect working "backup image" of your system when it's perfect, so you can quickly revert back for incidents like this.
when i said about boot time it was actually about loading Ubuntu screen after boot. i can see the black screen for a few seconds and then mouse pointer appear. then after few minutes top panel and wallpaper appear but top panel take few minutes to load time,shut down icon,Dropbox icon and Skype icon. Skype taking so much time to load too. but any of this doesn’t happened before. i have a back up but it was done via Ubuntu Mate backup wizard. i don’t think its “backup image” which i can load.
I forgot to mention, Clonezilla Live is a great tool to image the system when it’s not in use. (It may look a bit scary at first) The built-in backups is mainly useful for personal files.
One other thing you could try is logging in as a guest user and see if the performance improves. If it does, then we can pinpoint that your user profile is a bit bloated and has too much going on.
you are correct. I tried new user account and Guest account. Both were quickly loaded and look fast enough. That’s mean the things i have installed cost me the speed. working with new login is easy rather than reinstalling OS.
