Vivaldi Unresponsive After Docking/Undocking



  • I'm running Vivaldi on a Thinkpad (T530) with native resolution 1920x1080, and I dock with a setup including a 1920x1200 resolution monitor. I do not know whether the resolutions are significant here, but I list them anyway because I feel as though it might play some part. I'm running Win 7 Pro. Sometimes, after docking/undocking, Vivaldi becomes unresponsive, which I usually notice because it does not appear when I click on the taskbar icon. Sometimes I can kill it by right clicking and selecting close, twice, other times I have to use Process Explorer to kill the root process. Luckily, 95% of the time tabs are remembered, but occasionally the "kill" must have been more drastic and Vivaldi has reopened without any tabs. The problem has also existed for many versions of Opera, suggesting that it is an issue with Chromium. I have not tried using Chrome extensively, but occasionally I have it open and I have never noticed it suffering from this problem. Note that I have posted a nearly identical report on the Opera forums today: https://forums.opera.com/discussion/1866353/opera-unresponsive-after-dockingundocking#Item_1 Has anyone else who uses a laptop which is frequently docked/undocked suffered from this problem? How about anyone who does not dock, but who has a setup which changes resolution for some reason? Other Thinkpad owners?



  • Does anyone have any idea how I might investigate this problem? Can I do something like turn on logging and then grab the logs after it next happens?



  • Complete silence on both forums :) I'm guessing that this is not a common problem. However, surely there is some way that I can gather evidence? When you force-close Vivaldi, does it leave any files around that might give a clue?



  • I think I've got the lurgy :p No-one is touching this one with a barge pole!

    I suspect docking and undocking a laptop is a very rare use case. I don't know anyone who has a laptop dock.



  • Thanks for the reply! Perhaps you're right. Maybe I need to use Chrome for a period of time in the hope that it also suffers from the same issue, in which case I will have a large base of users to appeal to. It's a shame; I'm very keen to adopt Vivaldi full time. In fact, I did for a couple of months, and I loved what it has to offer.

    Here on my laptop Opera started to freeze/lock and I had to kill it. I started a new profile and now it's working correctly.



  • When you say profile, do you mean the synchronisation account? And under what circumstances would it become unresponsive?

    There are no synchronization accounts as yet.

    A "profile" normally refers to the user preferences and data folder. Sometimes, from build to build, things accumulate that cause problems with the functionality of later builds, and if you rename your profile folder and let the browser create a new one on restart, then you can have an install that basically behaves like one that was installed "virgin," but once you're sure it's acting right, you can transfer data like bookmarks, notes, etc. from the old renamed folder into the new profile folder and still benefit from a profile that doesn't have old accumulated errors in it.



  • Thanks. I forgot which forum I was posting in - no synchronisation here yet. Just noticed an epic failure on my part: I mis-titled this post with "Opera" instead of Vivaldi… I will try reinstalling Vivaldi as you suggest to see if that makes any difference.

    That's kind of funny. I have nearly made the same mistake any number of times. I feel at home here like I did on the old Opera blog, and Vivaldi is the heir to old Opera, so it's totally an easy mistake to make.

    I can't say, I tried to track it down, but it ended up being random and very frequent. (~10m)

    I suppose it could be related, but my problem does specifically happen between docking and undocking. I'm not sure whether it relates to the screen resolution changing or something else. Actually, could test the screen resolution theory. I'll do that and report back.



  • I started using Chrome and confirm that this issue does, indeed, also occur. This revealed that the problem is fairly well documented!

    It seems that the transition between the two GPUs on my laptop (nVidia for docked, Intel for undocked) is suspected to be the culprit. A work around is to go to vivaldi://flags and set "Enable GPU rasterization." to Disabled.
