Maximized windows extend below panel on primary monitor if taskbar too large

Bug Description

Binary package hint: compiz

I have an up-to-date i686 gutsy install on a Dell XPS M1710 laptop with an NVIDIA GeForce Go 7900 GS.

When I set-up TwinView, enable Compiz, and increase the size of the taskbar to well above the default in (right click on Taskbar) -> Properties, there is a point where maximized windows are no longer sized correctly (after re-maximizing them to get around bug 172716, of course). Instead of their bottom ending at the top of the taskbar, they go straight to the bottom of the screen. Their bottom is hidden behind the taskbar and thus cut-off. For me, this happens precisely whenever the size of the taskbar is 119 pixels or greater. (If it's relevant, the main monitor's resolution is 1920x1200 and the second monitor is 1920x1080.) This is unfortunate since my preferred taskbar size is 120 pixels.

Hi. Thanks for reporting this. Is this still a problem? Could you attach the following files for us: ~/.xsession-errors, /var/log/Xorg.0.log, and the output of lspci -vvnn.

Yes, this problem still exists. Note that I am using the 169.09 NVIDIA driver now (installed from hardy repos, with a workraround for bug 192524). I am attaching the requested files.

Changing back to New since I have provided the requested info.

The issue that you reported is one that should be reproducible with the live environment of the Desktop CD of the development release - Hardy Heron. It would help us greatly if you could test with it so we can work on getting it fixed in the actively developed release. You can find out more about the development release at [WWW]

I'm not sure if I can help you there: I tried installing the latest Hardy versions of the compiz packages a couple days ago, but compiz kept segfaulting on startup for me (which I have filed as bug 192545). If and when that is fixed, I'll let you know whether or not this bug persists in the current Hardy version. If I recall correctly though, I was using a previous set of Hardy compiz packages before that and the bug did persist in those.

Not sure if I should change this back to New or leave as Incomplete. I'll let you decide.

Thank you for your report. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you?

Thank you.

I am no longer using TwinView so this doesn't matter to me, but if you are asking if it still occurs then the answer is yes. Also, I have now tested with the Hardy versions of Compiz, the NVIDIA drivers, and the X server, and it exists there too. The value of 119 pixels is unchanged. I am attaching the logs from my X session when it repro'ed with the Hardy versions and changing back to New.

Btw, just in case you haven't noticed this, it occurred to me after I filed the original report that the cut-off value of 119 is almost exactly the difference in vertical resolution of the two monitors (120). Perhaps that is significant.

We were wondering if this is still an issue for you. Can you try with the latest Ubuntu release? Thanks in advance.

Hi. I am having this problem. I am using Compiz + NVIDIA TwinView and when I maximise a window it falls under the bottom taskbar. I'm attaching those files....

Andrew, are you using Ubuntu Intrepid?

Sorry I should have said that. Yes I am using Ubuntu Intrepid (GNOME).

Cool, thanks. Changing status to Confirmed since Andrew has verified that the problem still exists on Intrepid.

I was told this is my bug, but my taskbar is 24 issues high. So does that fall under bug 140860 or this bug? I still can't get maximize to not go under the panel on the monitor if the screen edge goes onto another monitor, and I think that's the underlying issue ... (on latest jaunty)

I'm using Ubuntu 9.04 (Jaunty Jackalope) on an Asus Eee PC 901 with dual head (internal plus external monitor). The upper and the bottom taskbar are placed on the external monitor. When I maximize a window placed on the external monitor, it touches the bottom of the screen instead of ending at the top of the bottom taskbar.

I confirm this bug too! I'm using ubuntu-10.04 (Lucid Lynx) with nvidia-195.36.24 and I see the bug.

I have the same problem with maverick: Dual monitors arranged vertically; top and bottom panel are on the same monitor; windows on the monitor with the panels maximize under the panel near the other monitor.

Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to look at all reported bugs in a timely manner. There have been many changes in Ubuntu since that time you reported the bug and your problem may have been fixed with some of the updates. It would help us a lot if you could test it on a currently supported Ubuntu version. When you test it and it is still an issue, kindly upload the updated logs by running apport-collect <bug #> and any other logs that are relevant for this particular issue.

I no longer use dual monitors so I can't help with this bug anymore. I'll leave it as Incomplete in case someone else is still experiencing it and can provide the info.
