The log seems to indicate that you're experiencing this Atom bug, so here is the right place... i915_program_error: Exceeded max ALU instructions (76 out of 64) Although the log also shows you're experiencing general Intel bug 1583949 too. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1580792 Title: Unity8 on Intel Atoms performs poorly (falls back to software rendering more than non-Atoms do) To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1580792/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Here is my unity8.log with INTEL_DEBUG=perf. It's quite obscure for me as I'm not a developer, but I did find the problems you mentioned it your comments.

[Bug 1580792] Re: Unity8 on Intel Atoms performs poorly (falls back to software rendering more than non-Atoms do)
The original bug description is a bit vague here. In comment #3 I was aiming to make this bug very definite. If you add INTEL_DEBUG=perf then you will see the errors I mentioned. I think this bug should be about those errors in comment #3 since the bug description is a bit too vague. Please add INTEL_DEBUG=perf to your /etc/environment to help us determine if you are experiencing this bug or something different. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1580792 Title: Unity8 on Intel Atoms performs poorly (falls back to software rendering more than non-Atoms do) To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1580792/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1580792] Re: Unity8 on Intel Atoms performs poorly (falls back to software rendering more than non-Atoms do)
Did a few tests, dialogs with a black/transparent backgrounds are definitely the worst (Terminal password prompt, shut down dialog, set a code or password in System Settings, connect to a hidden wifi network). The dialog can take up to 20s to fully open. Even then, they remain slow, for example when you type your password to unlock the Terminal (30s from the end of the splash screen to a workable terminal). Other dialogs also perform very poorly, for example the "new VPN connection" form, or the calendar-app's bottom edge (tested with the snap version) in which you can't really type anything. The alt-tab switcher is also very (very) laggy and completely unusable. The pointer only move every 1 or 2 seconds which makes it hard to aim correctly at anything. In all those examples, there is some kind of transparency layer involved. Could it be the cause? As noted in the title, performance is generally slow, so it might also be interesting to see what does work well. For example, tab switching in the browser (bottom-edge style) animates quite nicely once it's opened (though it's a bit slow to open). Moving around in the calendar-app is also quite smooth. I would have liked to test lists as well, but the address-book-app snap won't work and Dekko isn't in the repos (neither deb nor snap)… Let me know if there's any kind of test I can do or log I can provide. And let me know if I do have to file another bug! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1580792 Title: Unity8 on Intel Atoms performs poorly (falls back to software rendering more than non-Atoms do) To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1580792/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

well, if it is a dialog-specific problem it could be worth having a separate bug, that only tackles dialog. otherwise you end up fixing too many things as part of the same bug -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1580792 Title: Unity8 on Intel Atoms performs poorly (falls back to software rendering more than non-Atoms do) To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1580792/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@Guillame: that is interesting, it might be useful to see if that happens for all dialogs like that (there should be a few in system settings app).

[Bug 1580792] Re: Unity8 on Intel Atoms performs poorly (falls back to software rendering more than non-Atoms do)
Hi, I don't know if this is useful, but on my netbook the worst performance comes from black and transparent overlays, like when the Terminal asks for a password or when you want to turn off your computer. In those cases the frame time is more than 1s, sometimes 2s. I have to hard reboot every time because I can't click :( -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1580792 Title: Unity8 on Intel Atoms performs poorly (falls back to software rendering more than non-Atoms do) To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1580792/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
