[duplicate] Slow/lag after update (sublime-text-dev, atom, rstudio)

Update: I didn't find it in my original search as I think symptoms are manifesting themselves differently for various folks, but this post appears to be the same issue. I can confirm that downgrading to kernel 4.5.4 solved the issue for me. Please see that post for other ideas (like removing xf86-video-intel to use in the built-in i915 driver) and a link here regarding some possible intel graphics driver Xorg options.

I booted up to find that sublime-text-dev was running extremely lag-ish. Any action at all takes several seconds to complete (just arrowing around, clicking to move the cursor, basic stuff). I thought it was just sublime, and went on to install atom as I'd been thinking of trying it out. I got the same behavior. Happened to need to look at an R script using rstudio and found it, too, was doing the same.

top is showing nothing out of the ordinary, with the highest cpu consumers fluctuating between the usual: top, chromium, urxvt, Xorg. None ever feature higher than ~1-2%. According to free I'm using ~800k of ram, leaving just under 23G available. I have no idea what's up.

Here's a list of recent packages; I know sublime was working on Thurs or Fri last week, so if it's a package it should be one of these.

Other details:

- nvidia with bumblebee
- openbox

I haven't started troubleshooting yet by downgrading as it's late and I need to go to bed. I wanted to post here in case there were any suggestions for where to look. Do sublime, rstudio, and atom share any common backends that might be acting up? I don't notice anything odd from Chromium, urxvt, thunar, or emacs (just some applications I've used while this was going on).

Thanks for any suggestions.

Re: [duplicate] Slow/lag after update (sublime-text-dev, atom, rstudio)

A few day ago i ran into the same issue (sublime-text lagging; being unuseable after full system upgrade). I "solved" it for me by downgrading the kernel back to 4.5.4-1.

cd /var/cache/pacman/pkg
sudo pacman -U linux-4.5.4-1-x86_64.pkg.tar.xz

But i see that you already had newer kernel versions installed. I did experience the lagging of sublime after upgrading to linux-4.6.1-2-x86_64 from 4.5.4-1.
(i run arch on an thinkpad t540s)

I know that this is not a valuable solution - sry my ignorance about this. I had to finish my work.

Anyone has a clue what could cause this problem?
A regression in intel graphic drivers?

Re: [duplicate] Slow/lag after update (sublime-text-dev, atom, rstudio)

@g8ntly: thanks for the tips! I think I didn't go back far enough in my pacman logs and must have updated everything without rebooting or something. I thought it was the change from 4.6.1 to 4.6.2, but after finding the thread I just linked to above (as an update), I saw folks mentioning 4.5.4 and sure enough that update was just a day or so before.

Take a look at the threads I linked to above; it seems like it's exactly an issue with intel graphics. Would never have suspected that as I use bumblebee and thought it might be related to dkms-nvidia, which is where I started troubleshooting (replacing dkms-nvidia with standard nvidia, reverting nvidia and nvidia-utils, etc.).

Anyway, I don't love the solution as one has to watch linux with every update until some solution comes about. For some, it seems that just uninstalling xf86-video-intel works, and in the second link someone has some kernel line options that seemed to help. Thanks again and your comment reminded me to mark this as a duplicate since all the action is going on in other threads smile
