Version: 1.7 (using KDE 4.7.1) OS: Linux Until kde 4.5 Dolphin started very fast with no gap beetween the mouse clic and its appearing on desktop, it was almost instantly. In kde 4.6 and kde 4.7 it lags 3-4 seconds before open. It's always reproducible and occurs: 1- even if another Dolphin window is present on screen (in order to exclude cache issue) 2- with kwin effects on AND off (in order to exclude possible 3d acceleration lags or video driver problems) Im'using Kubuntu and I know until Maverick HAL was used, in Natty and Oneiric it has been replaced by udev, maybe it could be a possible cause. Because of this I can add every kde application which makes use of some sort of Fyle system Navigation plugin is extremely slow to start and to appear on screen: - applications that open a "File chooser Dialog window", like Konversation DCC dialog window - applications the have a built in File system browser, like Gwenview which opens very slowly too - even Kate text editor is slow at default configuration until you leave File system Browser plugin checked. If you uncheck it to disable the plugin Kate becomes fast again to start and open its window. Reproducible: Always Steps to Reproduce: Simply launch Dolphin, or Kate with File system Browser plugin enabled, or let Firefox open File chooser dialog window before the download starts to see gap in seconds beetween the mouse action and the window to appear Expected Results: Until kde 4.5 Dolphin and in general File system browser/File choosing windows were very fast with no lag beetween launch and there appearance on the desktop OSs: Kubuntu Maverick 64 bit (no issue), Natty 64 bit and Oneiric 64 bit (they have issue described) Hardware: Intel core i7 Nvidia vga with official drivers 3 hard disk, the first with 2 partitions, second and third with 6 partitions each
it occurs to me too. I'm on precise with kde 4.8 rc1 and dolphin starting is inexplicable slow. It aparently does nothing, the hard disk doesn't load but dolphin start with a couple of second of lag. I've 2 hard disk with 6 and 8 partitions respectively on them and I suspect is this the culprit, the time needed to have answers from the hdds at start. Tried a live kubuntu precise cd on a laptop with only 1 hd and 3 partitions and dolphin open fast.
It's a network related problem but I don't understand why it happens. Try to disconnect from network and check if it occours.
thanx for your reply, guys. I've tried with my network disconnected (cable unplugged from the computer) but I'd say there's no difference, it's still lagging a lot. As shimon pointed out it seems related to the number of partitions dolphin has to read when it opens, I've a lot of them on my system. I reproduced his example, an ubuntu live cd, oneiric, on a pc with only one hard disk and there dolphin opens very quickly (though not as fast as in kde 4.5). I must add I'm now on ubuntu development branch (precise) with kde 4.8 rc2 and here dolphin seems faster again, almost the same responsiveness it used to have in kde 4.5, and again network enabled or disabled seems to have no effects at all.
Created attachment 67773 [details] The archive contains the output of "strace dophin" command I added a strace dolphin output, hope it can help
Does the problem also occur if you hide the "Places Panel" (F9) on the left?
(In reply to comment #5) > Does the problem also occur if you hide the "Places Panel" (F9) on the left? yes, the responsivness doesn't change if the "Places Panel" is closed and dolphin restarted. The same occurs in Gwenview opening it via double click on an image, there is no difference if sidebar with folder browser is hidden or showed, it lags. Kate speed, otherwise, is effected by "Browser filesystem" extension: if it is enabled Kate lags at start, if it's disabled Kate regains its speed. But I'm now on KDE 4.8 RC2 and something seems to be happened between 4.8 RC1 and 4.8 RC2 because now dolphin, gwenview and kate with that extension enabled are way faster than before (faster than in KDE 4.6, 4.7 and 4.8 until RC1). KDE 4.5, though, was the fastest of them, I still have Kubuntu Maverick installed on a partition (with KDE upgraded by Kubuntu PPA to the 4.5 version) and there Dolphin is blazingly fast, it opens almost instantly after the mouse click, the same happens for gwenview.
I have seen a similar report in a forum and it was solved by downgrading xorg-server. maybe this is not a dolphin/gwenview but after all? Is the rest of the system responsive while dolphin is starting? can you move the mouse cursor smoothly or type in another window?
Hi Fabian, I tested Ubuntu with the same X server version and nautilus opens immediately after the click, dolphin and gwenview still lag. As said previously it's now (4.8.2) way better than before but still, it's not as fast as it was until kde 4.5.
Dolphin takes 4-6 seconds to launch compared to windows explorer "1 second" launch time! I hope this gets resolved.. despite the launch lag, Dolphin still remains the #1 File manager in my opinion. I'm using Kubuntu 12.04 with KDE 4.8.3.
Resetting assignee to default as per bug #305719
If this also affects Gwenview, it is probably not a Dolphin bug. Could anyone who can reproduce this try to run Dolphin in gdb and obtain a backtrace while it locks? ("gdb dolphin", then "run", when it locks, press Ctrl+Z, then "bt").
when i start it from a console mode: "/org/freedesktop/UDisks2/drives/MATSHITADVD_RAM_UJ8B2_HM33_008954" : property "Drive" does not exist "/org/freedesktop/UDisks2/drives/PLEXTOR_PX_128M5M_P02310102061" : property "Drive" does not exist "/org/freedesktop/UDisks2/drives/Samsung_SSD_840_PRO_Series_S12RNEACC41938F" : property "Drive" does not exist "/org/freedesktop/UDisks2/block_devices/dm_2d0" : property "Name" does not exist "/" : property "DeviceNumber" does not exist "/" : property "Device" does not exist "/" : property "MediaCompatibility" does not exist "/" : property "MediaRemovable" does not exist "/" : property "Removable" does not exist "/" : property "ConnectionBus" does not exist dolphin(5771) KSambaSharePrivate::testparmParamValue: We got some errors while running testparm "Load smb config files from /etc/samba/smb.conf Loaded services file OK. ERROR: pid directory /var/run/samba does not exist that took like 15 seconds to start with kde 4.10
I'll close this for the time being because there is no way to know what the problem is until we have a backtrace that tells us where the freeze occurs (see comment 11). It's most likely not a Dolphin isse though. Comment 12 indicates that it might have something to do with Solid/UDisks2, which seems plausible. Thanks for your help.
The same symptoms are affecting me right now - it tooks over 10 secs for both dolphin and gwenview to start. I recently update both KDE (now 4.10.5) and xorg-server (1.14.2-2) so it may be related... It is also worth noting I have CIFS share in fstab and it is shown in the KDE places panel.

If I can provide any cooperation hunting the bug, let my know.
The backtrace shows that it's a Solid issue, so I'll reassign (note that installing kdelibs debugging packages might make your backtraces more useful). It looks like it's waiting for a response to a synchronous D-Bus call. Not sure if anything can be about this easily in KDE 4.x (AFAIK, Solid will be completely asynchronous in the KDE 5/Frameworks era).
*** Bug 323094 has been marked as a duplicate of this bug. ***
I could reproduce today after updating udev/systemd to latest openSUSE Factory version (206 something). The issue was upower not running correctly. Going back to stable (195) resolved the issue.
Hello! Sorry to be the bearer of bad news, but this project has been unmaintained for many years so I am closing this bug. Please try again with the latest version and submit a new bug to frameworks-solid if your issue persists. Thank you!
