Debian Multimedia :: Basic Qt App Doesn't Redraw Window Properly
Jan 25, 2011
When I run it, the window shows up but Qt doesn't draw in the background. I end up with phantoms from windows behind it: URL...The window will draw the background correctly when I resize it -- MOST of the time. And sometimes there will be a noticeable delay between resizing and drawing in the window.Am I missing some libraries? Is this a bug? Maybe there's something else I can look up to find a solution?
I'm running sid, my window manager is fluxbox, and my video card is a GeForce FX Go5200 64M.I should note that this works perfectly well on another computer I have that's running sid as well.

I've compiled a basic Qt app as given in this tutorial: [URL]... When I run it, the window shows up but Qt doesn't draw in the background. I end up with phantoms from windows behind it: [URL]..The window will draw the background correctly when I resize it -- MOST of the time. And sometimes there will be a noticeable delay between resizing and drawing in the window.
Am I missing some libraries? Is this a bug? Maybe there's something else I can look up to find a solution?I'm running Debian sid, my window manager is fluxbox, and my video card is a GeForce FX Go5200 64M.

I find xcompmgr more than adequate for making a desktop look pretty modern, and I don't like the more extravagentCompiz gimmicks - but there is one thing that irritates when using xcompmgr which someone here might have worked round.
Rounded window borders don't draw and redraw properly when using the Terminal (gnome-terminal and the LXDE and Xfce ones) or system monitor and moving them from their default place. You get this little white botch at the corners. I'm not massively technical and I'm ambivalent about how much more I want to learn as I have plenty of creative outlets already, but I would like to solve this. Somehow xcompmgr is treating these programs as a different class? It's capable of drawing the window borders properly as it is just these two programs that get botched. Possibly this doesn't get noticed as maybe people usually use xcompmgr with openbox and LXDE and their square window borders. I did do a search but there was nothing matching what I saw.

redrawing windows in KDE is very, very sow (since 4.4 or so I guess, but maybe it was always like this). When I switch to a desktop running Kopete and Amarok, it takes like 2-3 seconds to redraw the applications. GTK apps are faster to redraw, although far from ideal. This happens both with the effects enabled as well as disabled. When the effects are enabled, it's faster, but still very slow.
When switching apps or desktops in Gnome with Compiz running, it's almost instantaneous... I don't think it's because of any particular effect like Blur, because I've disabled them all, though the compositing is up (e.g. the bar is transparent, but all other effects are off in KWin). On the other hand I have plenty of effects enabled in Compiz and it's still ways much faster.
I have ATI Radeon X1200 integrated card, using the radeon driver 1.6.13.2 (I'm not sure whether is it from experimental or Sid, but I don't think it matters, since the older versions were slow the same) without any particular configuration from my side (i.e. no xorg.conf).On my other computer with either quite powerful NVidia card or an Intel card the performance is the same in KWin and Compiz...

I know the problem has been partly solved in this old thread [URL] .....
Now we have Jessie as stable, yet LXDE doesn't shutdown properly:
On the same computers, Wheezy LXDE shut down very fast
I installed Jessie from the netinstall image.
On a 2007 computer, it's like the old days with a Pentium II running some version of Puppy Linux or Slitaz. The system shuts down after a while but the computer remains on.
On a 2013 laptop, I added the line init=/bin/systemd in the Grub default file as advised on the old thread above. The laptop shuts down after a while, the system first, then the hard disk goes to sleep, then all the leds are off.
If I run the magic command, the computer shutdowns in a breeze, perhaps even quicker than good old Wheezy:
Code: Select all# systemctl poweroff
Now, is this still a systemd bug? Doesn't look like it since the systemctl command works. Is it an LXDE bug? Looks like it in a way - if the LXDE shutdown button enabled the systemctl poweroff command, I suppose the button would work?
Is there a way to make the LXDE shutdown button run the systemctl poweroff command?
I'm glad Wheezy is still with us because I wouldn't install Jessie for newbies — they'd think shutdown (through clicking on a button) is even worse than in Windows.

with 11.2 and now with 11.3 (using KDE4) i got two issues with emacs:
1) The emacs window doesn't properly snap to other windows. There is mostly a small gap inbetween.
2) When switching between buffers with C-x b the emacs window shrinks vertically from below!

Yes im refering to Windows Degrade and how over time windows just running will degrade and start causing errors. DLLs go missing and bizzare things. Ive seen wierd things happen on a windows machine that is dedicated to one function. Well to my point, recently I have been having many linux issues, not like normal or anything throughout the years I have experimented with linux though.
1)entering fullscreen on VMware crashes linux sometimes (no Ctrl+Alt or Ctrl+Alt+F2 ect)
2)using a different monitor haults the virtual machine while other monitors do not (I have 4)
3)Java apps freeze and require moving the window offscreen (below the screen) to redraw
4)general linux freezing
5)glitch with xinerama that repeatedly teleports mouse between two monitors causing the system to be unusable (no Ctrl+Alt+F2 or anything either)
At first I thought they were all related to VMware but they may not be. I run VMware everyday for my slingbox and light EXE-ing when wine isnt an option. So I may not be asking for fixes to all these problems but whats going on? Ive seen linux installs last years and believed linux to not degrade.

Sorry if this is a dumb question, there's a lot about networking that I don't get yet. I've got two computers using the same wireless router. They both get their IP addresses via DHCP from the router (I assume). If I want to connect from one machine to another, I can use the IP address (which works), but it's a pain checking what the IP address is, I guess it depends on which one connects first? So it might work today but tomorrow the IP addresses are reversed and the same command wouldn't work.
What I'd like to do is just refer to the other computer by name, but of course I haven't got a DNS server just for these two computers, and I don't think the router can do it (can it?) so is there a way to do it? Is it really just a case of switching off DHCP and giving each computer a fixed and unique IP address, and then entering some name in the hosts file for the two computers? Although then there's nothing to guarantee that the name in the hosts file actually matches the hostname of the computer at that IP I suppose.

The web cam on my Dell Inspiron mini 10 doesn't work properly. Cheese only takes very dark pictures but no video and the main screen stays dark all the time. Skype transmits a very dark image, too. How can that be tweaked.

By pressing 'properties' on a folder it freezes and I have to do killall nautilus && nautilus to get it working again. I have found no fix when googling (saying some packages that isn't installed is the problem).
It just takes a really long time to load based on the CPU usage.

I have a minimal debian install, with not much more than enough to run scrotwm, I want to change the basic arrow cursor to a png I have. Is there a simpler lower level way of achieving this without having to install and modify an existing cursor theme. I installed x11-apps just to get xcursorgen... though idk if this has been an essential step or not. Anyway, I have run it on my arrow.png/arrow.cursor to create a "default" cursor file... though am lost as to where to go from there. I have no idea where the existing default cursor is located, though i suspect it's a font cursor not a icon cursor...

I'm trying to install debian on my HP laptop but get the following problem...
After the live CD boot screen shows up i go to XFCE > install
it loads vmlinuz and init.gz and after that the screen goes blank
i tried graphical install, advanced install, advanced graphical install but those too didn't work
also i tried all of these from LXDE menu
but the same problem
My laptop is HP pavillion dv6
its got an ATI radeon graphics card (hope there's no problem with the display)

However the cd works fine with my old desktop computer
which has no graphics card
256MB ram

I recently installed the XFCE spin of Debian (amd64) on my Lenovo L440. I tried installing it before, but apparently the 3.2 kernel that ships with Wheezy doesn't properly support the proprietary firmware for the wireless card, blah blah. So I wound up using Windows 8.1 for a bit, and then Fedora (boo). Anyway, with the wheezy-backports kernel (3.16.7-ckt4-3~bpo70+1) everything works like a charm. Everything, that is, apart from the sound card — the entire system is completely mute. Well, apart from the system beeper. I searched the forum and found another thread, but that guy was (for some reason) just running dwm — I figured XFCE might feature a more complete sound system. But maybe the output he gave will be useful in my case as well:
Code: Select alleirik@gerhardsen:~$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: HDMI [HDA Intel HDMI], device 3: HDMI 0 [HDMI 0]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: HDMI [HDA Intel HDMI], device 7: HDMI 1 [HDMI 1]
[code]...
I also tried running alsactl init (as root), which doesn't appear to have made any difference.

I installed debian and want to install compiz (properly).Read this thread Compiz and followed the instruction to install the packages. It mentions xorg.conf which does not exist where it tells me to look.I can type "compiz --replace" and it does do something but all the window borders disappear. I tried compiz setting manager - still same problem.And no visual effects (presumably due to missing xorg.conf)

I just recently acquired a PII 333 w/ 160M ram (I know, grossly underpowered for anything by today's standards) but mostly wanted it for internet & to use for printer / scanner & camera stuff. So, while checking it out I tried a few live cd's on it (fedora 10 & a ham version of puppy linux) the puppy worked just fine but the fedora "puked" when it got to the GUI (I had this happen with F11 on another computer) The thing that confuses me is, doesn't fedora's live cd have a basic, generic (like a vga 640 x 480) driver that SHOULD work with any video card & monitor or am I missing something here?

If you don't know, users are able to quickly resize windows using the "ALT+MiddleClick" key shortcut/combo. Basically, hold the ALT key, and mouse middle click and hold on a window. Move the mouse around, and it will resize the window for you.
STEPS TO REPRODUCE:
1) Open a single Window.
2) Near the bottom-right-hand corner of the window, ALT+MiddleClick and drag. It should resize. Great. It works.
What Doesn't Work:
Now, the problem arises when you have multiple windows open on the desktop, they are "layered". i.e. you might have several windows open "behind" the one currently "up front". Example:
If I try to ALT+MiddleClick the "foreground window", it rarely actually resizes THAT window, and instead jumps one of the windows from behind to the front, and resizes that one instead!
STEPS TO REPRODUCE:
1) Open 3x gnome-terminal windows and say some nautilus window. Place them overtop one another. (like the above image)
2) Try to ALT+MiddleClick the foreground window.
3) Repeat this always trying to grab the foreground window.
For me, the window manager seems to bring some window from the background to the front! Desktop Recording of the Problem: [URL]
Running:
* Ubuntu 10.10
* compiz window manager (the problem does not occur with metacity)
* ATI Radeon RV770 (HD4870) w/ open source Radeon Driver (same problem w/ fglrx driver)
* Versions: [URL]

How to get compiz to auto-start. What seems to be the generally accepted method (from what a few google searches and the debian wiki tell me) of using gconf-editor and changing the window manager from 'gnome-wm' to 'compiz' in desktop > gnome > session > required_components doesn't change anything. The only method I found that did not involve using a terminal and running 'compiz --replace' every time I boot the computer was to add compiz and fusion-icon to the gnome startup apps, but this causes unwanted flickering (it starts metacity and then replaces it with compiz, ie it's simply automating what I would do with the terminal). Autostarting the fusion-icon alone does not start compiz, although it allows me to start it from it's menu if I right click the icon. Note that I sometimes use fluxbox as well, so starting it on boot isn't really an option either.
Perhaps this can be useful :
compiz:
Installed: 0.8.4-4
Candidate: 0.8.4-4
gnome-session:
Installed: 2.30.2-3
Candidate: 2.30.2-3

I guess this is a part deux, since I already posted one rendering issue which was eventually resolved ... having to do with the themes of this Debian Forum. Well, I don't know if this is related to that, but yesterday I noticed on another site that my Iceweasel 4.01 is not displaying portions of pages properly. See attached images. Both Chrome & Opera display that page correctly, I've included a screenshot of the same page with Chrome. I have JAVA installed and everything works perfectly fine accross the board on all browsers, except for this "once in a while" issue with Iceweasel. I've noticed this "missing content oddity" on three sites so far (out of 50 or more). No problem with eBay, craigslist, paypal, and other major players.
Open the images with a new tab, then compare both images side by side for best results.

I just wounder why a ntfs partition need that my window xp shut down properly before i can mount it on my new Debian install.What happen it that when scanning window xp for virus i got a blue screen and window just crash repeatedly , so i tough i could just mount that partition with ntfs-3g, find the virus witch i identify to be in c:/window and delete it, but my ntfs partition would not mount and the boot message said something like (ntfs partition is still in use). Long story short, i finally managed to get a full window xp boot followed by a clean shut down, then my ntfs partition mounted and i was able to delete that virus.I could mount that partition with ntfs ro option in fstab, but not with ntfs-3g rw until i got a clean xp shutdown.

Everywhere but the actual webpage is transparent in the firefox window. I can't really see the main toolbar with file, edit, tools, etc. It crashes when I try to click add-ons in the tools drop down menu. It also makes my computer run slower and freeze up. Thinking it could be a bug from a recent update not sure because I think it started after tabking or another add-on was updating. I'm using firefox through wine right now. Using Ubuntu 9.10.

xdm which refuses to load a window manager. I run Debian squeeze. xdm tries to execute /etc/X11/xdm/Xsession, which is actually an empty file, and fails with the error 'too many open files'. Afterwards xdm terminates the session and executes Xreset. Here the entries from the log:
Sat May 22 11:27:19 2010 xdm info (pid 2246): sourcing /etc/X11/xdm/Xsetup
Sat May 22 11:27:23 2010 xdm info (pid 2246): sourcing /etc/X11/xdm/Xstartup
Sat May 22 11:27:23 2010 xdm info (pid 2275): executing session /etc/X11/xdm/Xsession
[code]....
I was unable to find anything valuable concerning this problem. This is kind of annoying because I always have to switch to a console, stop X and startx X manually using startx. Then everything works out just fine. Unfortunately I am not yet that familiar with the setup process of X.

I'm deciding to go with a window manager instead of a desktop environment. I want to go simple and lightweight, and I know a lot of you run window managers such as openbox, fluxbox, and some tiling ones like xmonad, awesome and dwm. I want to give xmonad a try. For those of you who run tiling window managers, how do you know what is running in the background? There is no system tray in a screenshot such as this: [URL]. I'll be playing around with xmobar because that seems to be a popular panel with xmonad, and that's what's in that screenshot.
Also, how do you run your programs? You don't run it always from the command line, do you? When I want to run Chromium, I have to start up a terminal and load it that way, having the terminal and the browser open when using the browser. I know other window managers like openbox provide a right click menu, but xmonad doesn't (or does it?). I know a lot of people who use tiling window managers also use a lot of console apps, and I like that feel, but I don't think I'd want text for everything, such as the web.

Previous X was 1.4.2. After aptitude upgraded X Window to 1.7.7, startx crashed complaining: XKB could not find /usr/share/../rules/evdev file. There is no evdev file.
How do I modify xorg.conf to work with evdev? I spent few hours to figure out evdev. It seems it's new style of managing input devices in X Window. The information isn't friendly to migrate from old to this.
When I put Option "AutoAddDevices" "off" in ServerLayout section, it literally froze X Window. X started without mouse/keyboard control. I had to turn off power switch. Now, I can't use X at all unless I move back to 1.4.2.

I have a couple of questions and one problem regarding my AMD64 Testing box. According to this Debian Xorg Wiki : Xorg is the default X Window server since Debian 4.0 (etch). It replaces XFree86 and is maintained in Debian by the XStrikeForce. But...it appears that I don't have Xorg as my X Window server, but rather XFREE86? I just checked my i386 Testing box, it does have /etc/X11/xorg.conf
[Code]...
The problem: I have lost my higher screen resolutions after today's apt-get dist-upgrade. I only have 800x600 and 640x480. I probably won't complain about these resolutions in twenty years or so, but for now, I'd rather get the higher resolutions back, ha.

I'm hoping that this is a stupid question with a very simple answer that I just can't find.I've been playing around with compiz-fusion on -current64. When I have two windows open, if I close the top, active window, I would expect that the next window in the stack would receive the focus. However, it does not. I have to alt-tab to it or click it with the mouse.
