Thank you for taking the time to report this bug and helping to make Ubuntu better.
Bug reporting is about finding & fixing problems, thus preventing future users from hitting the same bug. You seem to need support more than have issues with a bug (your issue could be hardware related or lots of things). In your case I would boot do a memory test of your system, check your hdd/ssd health (ie. `smartctl`, `gnome-disks` or KDE partition manager) and if easily done, open your box and do a quick 'cap check' (not easily done on notebooks!). I would then likely use a 'live' system (eg. Ubuntu install media, and selecting 'try ubuntu', but I'd also likely use a different release or something else) to see if the issue is resolved (ie. or configuration issue) or continues to occur. But this are support issues and not related to bug-reports. This bug report can be converted to a question (which is aimed at support). You can also find help with your problem in the support forum of your local Ubuntu community http://loco.ubuntu.com/ or asking at https://askubuntu.com or https://ubuntuforums.org, or for more support options please look at https://discourse.ubuntu.com/t/community- support/709 -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1851334 Title: Performance is not good system freeze a lot of time To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1851334/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
