I had a problem for a while, with PHPStorm being laggy on ubuntu (had this problem for over a year) Recently lag became unusable, after I tweaked a few things in ubuntu config (i think I increased swappiness) In Intellij discussion they linked to this linux kernel ticket.
Lags in a way of: Phpstorm window freezes for 5 seconds sometimes phpstorm does not unfreeze, need to kill the process laggy scrolling inside Phpstorm file window sometimes freezes inside settings menus laptop fan spins up audibly more than usual google chrome can become laggy while running phpstorm Ubuntu 18.04, kernel 5.3.0-51 pc: lenovo t480, graphics: intel 620 CPU: Intel® Core™ i5-8250U CPU @ 1.60GHz × 8 Could not figure out how to upgrade kernel version, because I already had stable one Upgrade to 19.10 did not help, kernel stayed the same version After I did upgrade to 20.04, it seems so far that problems disappeared. Now kernel is 5.4.0-29-generic -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872001 Title: 5.3.0-46-generic - i915 - frequent GPU hangs / resets rcs0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1872001/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
