Ubuntu :: Unity 2D And No Effects At Bootup - Firefox 4.0.1 Won't Run
May 2, 2011
I have had 11.04 running very well (without Unity) on my older Presario 2170us laptop. I've been curious about Unity, which my laptop can't run....so last night, I opened Synaptic, entered Unity as a search and saw 'Unity 2D'. The description indicated it would run without accelerated graphics cards, so I installed it.... and it killed Firefox 4.0.1 Now, even if I select Ubuntu No Effects at bootup, Firefox won't run.... instead, I get an error dialog, stating that a report will be send about the error and then I can click on either Cancel or Restart Firefox (which does nothing, by the way). I haven't tried uninstalling 'Unity 2D' because I wanted to post here first and see if there's a work-around.
I have just installed Ubuntu 11.04 on my laptop. Default installation, nothing special or fancy. It has a QuadroNVS 110M video chip, iirc. On Ubuntu 9, the visual effects were there to be enabled. When I enabled them it would ask if the proprietary drivers may be enabled. If I choose yes, they did and there were the visual effects that we all adore so much.
Now I'm trying Ubuntu 11.04, and the visual effects are nowhere to be found. The funny thing is, right after installation, the very first time the desktop was supposed to be loaded, I got a message telling my that my hardware is not capable of Unity. So alright, let's just only have the visual effects then. But how/where? It seems as if all references to effects and to unity have been wiped clean, because I can't find it *anywhere*.
Also, in the "additional drivers" I have activated the "[recommended]" nvidia accelerated driver, but after that (and rebooting) it is "activated but not currently in use". I have no idea what that means.
Note that I'm a Windows user really. I have next to no knowledge about linux. So great if I have to do some clicks or some packages to be installed, not so great to muddle in config files. I have also already scouted google, and I did find the obvious links, and no solution.
After rebooting, the first message i've been shown was: "Your hardware doesn't support Unity". First strange thing: Unity was working perfectly on all the Beta live versions I've tried before the upgrade.
Well, not a big problem, I didn't really like Unity. Let's stay with Gnome + Compiz, I said.. but Compiz effects don't work anymore. When I try to do System --> Preferences --> Appearance, the "effects" tab doesn't show anymore. The file named "screenshot1.png" will show you this problem, even if it's in Italian: there are only the Theme (tema), Background (sfondo) and Fonts (Tipo di carattere) tabs. Also look to the strange, fuzzy right corner of the themes previews. This didn't happen on 10.10. 3d rendering should be working, since I get
Code: glxinfo | grep rendering direct rendering: Yes But nothing works.
System->Administration->Hardware is empty, but it has always been empty, even on 10.10 (but Compiz effects were working). When I try to set Compiz as windows manager in Compiz Fusion Icon, sometimes the title of the windows disappear, along with the minimize, maximize and close buttons. Do you think there's something I can do to fix all these things?
When I first did the upgrade to Natty, no desktop at all would start. I could only get a text terminal login prompt. Log showed a segfault in fglrx module: "firegl_SetSuspendResumeState" I found instructions to remove the fglrx module and install the default ATI driver. Now I get a graphical login screen. But I must only login with "Ubuntu Classic (No effects)" in order to get a desktop. If I select Unity or Ubuntu Classic, I never get taskbars or menus and can't run any apps. So Natty Narwahl is a big step backwards for me. What is the relevant information to provide? The display driver is listed as RV710 [Radeon HD 4550] from ATI Technologies Inc.
since some time I notice a real disturbing video effect: I use Firefox 4 and Adobe Flash 10 (current version). When opening a web page which contains a flash video this video keeps part of the screen on both (!) desktops. (see attached pictures) Closing or minimizing all programs the video window is invisible. The video window will appear each time a program - any program! - window does appear above the area where this video windows is placed. I open Kate or OpenOffice or any other program and video window will appear again - see pic #1.
No matter if the video was started or not, the effect does happen everytime. No matter if the FF tab or the entire browser was closed or not, the effect will stay until X-Server restart. Even if I switch to the second desktop, the effect will appear. For example I launched Virtualbox on the 2nd desktop, open a Win XP system - the entire desktop background is blue. I opened Chrome and the video window from desktop #1 appears within the Chrome window. (see pic 2) The effect will not appear into screendumps, so I used my smartphone cam for both pictures:
#1: after opening www.tagesschau.de I closed firefox and re-opened FF with another web page. You can see the video screen from tagessschau.de within the heise.de page.
#2: then I switched to desktop #2, run WinXP into a Virtualbox window and launched Chrome.
Nvidia Gforce 9800 GTX+ current Nvidia driver from nvidia.com Kubuntu 10.10 amd64 and KDE4 all updates installed
As I do remember this effect happens since Flash 10. Unfortunately it is nearly unimpossible to use Internet without an installed Adobe Flash 10. If it would be possible I would remove Flash immidiately from any computer.
After maximising Firefox in natty the top panel and sidebar are not accessible.when I press F11 the close max and min buttons appear in the top right corner, but the window is still full screen it makes it very hard to access other open windows. Has this bug been reported.
when I click fullscreen in BBC iPlayer or ..... or whatever, the whole browser crashes instantly, no warning. And secondly my visual effects aren't working. When I go into Appearance and try and change from 'None' to 'Normal', it says 'Searching for available drivers' for about 20 seconds, and then says 'Desktop effects could not be enabled'.Both visual effects and fullscreen flash worked fine until about lunchtime today, and I honestly can't think of anything I did that would've changed setting or messed something up, so I really don't know.
When Unity is disabled, you can delete a bookmark from Firefox by right-clicking on the bookmark, under the bookmark menu, on the Firefox menu bar.When Unity is enabled, you cannot delete a bookmark from Firefox by right-clicking on the bookmark, since a right-click behaves the same way a left-click does. In other words, there doesn't appear to be any context menus.I reverted to the so-called "Classic desktop." There are other aspects about Unity I take issue with, but I will not go into them here.
If the Unity desktop is to be the default desktop for Ubuntu, then it must retain, at a minimum, mind you, the same functionality that was provided by the prior desktop. Access to an application's context menus is one functionality I see no good reason to forgo.
I upgraded from Ubuntu 10.10 64bit to 11.04 64bit. When trying to launch Firefox from any area (launcher, menu and terminal) It crashes the moment it tries to start. This only happens in the new Unity UI. Switching back to Ubuntu Classic, Firefox runs just fine. Here is the message I get when starting Firefox from the terminal:
1. I didn't like the icon theme and changed it to Ubuntu Mono Light. But is there a way to get the Min/Max/Close buttons to how they are in Radiance when maximized, or is that dependant on something else?
2. Is there a way to disable the Unity dock, but not the Unity feature where the Min/Max/Close go into the command bar?
Just moved to Ubuntu 11.04 with unity and only have one problem...For most of my desktop needs I prefer to have the Unity Launcher up all the time (fullscreen apps don't cover it), and have set this option with ccsm.
However, when I watch mythtv, it is also under the launcher (and the top panel as well). How can I force mythtv to cover the launcher? What I really need is a keyboard shortcut to hide the launcher, but the only shortcut is for "show launcher". (I guess the devs assumed everyone would want it hidden by default).
This, by the way is not my usual way for viewing mythtv. I have a projector attached to the desktop PC and it doesn't get a Unity Launcher by default (in Twinview), so no probs. However, occasionally I want to watch something on my computer screen, and that is when this issue arises.
So I'm interested in using Jokosher as an alternative to Garageband, which is what I'm used to using for recording music. After messing around with it a bit I've encountered a couple problems.The first is that Jokosher doesn't seem to remember the audio input device I selected the last time I used it. This may seem like a minor complaint, but I like to use my computer sort of like a tape recorder - that is, I use it to jot down quick musical ideas for later reference. With Garageband my internal mic is automatically selected, so all I have to do is press record. With Jokosher, however, I have to select the input I want to use every time I open the program. This, to me, kinda defeats the purpose of using a computer as a quick note-taking tool. Is there any way to set a default audio device for Jokosher to use, or to somehow make it remember which device I selected the last time?
The second is that I don't know how to install effects for this program. When I press the "effects" button it tells me that I need to install LADSPA-compatible effects myself. I've done a little bit of googling and still I can't figure out how to do this or which effects I should get.
im using the ubuntu distro and when i goto the visual effects tab and click on normal or extra, it says "desktop effects could not be enabled" also, i have Two hdd's, a 100GB that has windows 7 and ubuntu. and a 250GB that has Windows XP. GRUB didnt notice windows xp though, so its not a boot option.
I have ubuntu 10.04 , It was working fine the first time from USB . I tried to install ubuntu on my harddrive that had vista on it. But it gave me some error. And when I try to open it from hard drive its just blank screen.
And booting from USB doesnt work it comes on loading screen and doesnt do anything. This is what error I get when I press [esc] button
Code: Stdin error 0 /initial: line 7: can't open /dev/sr0: no medium foun unable to open '/dev/sda'
Up until recently have always been a gnome or xfce user, recently decided to try kubuntu. I like it, but its very slow to boot. I get a blank blue screen (same shade as grub) right after grub has finished its countdown and starts Kubuntu.
I downloaded the x86 10.04 LTS ISO and burned to a disc. I booted it on my old Fujitsu laptop but it just hangs at:
Code: Begin: Running /scripts/init-bottom ... Done. init: ureadahead-other main process (1019) terminated with status 4 init: ureadahead-other main process (1020) terminated with status 4 * Setting sensors limits [ OK ]
I tried all the possibilities like noacpi but to no avail.
I had Ubuntu working perfectly until I installed two Nvidia updates. (proprietary driver)Now Ubuntu freezes at the Ubuntu loading screen. Unfortunately I can't remember how to access the terminal at bootup, does anyone know?Im not sure what I will try yet but I might just try getting updates in case I will get a new Nvidia update to fix this.
In the past (before UpStart was used in Ubuntu) I was able to configure multiple boot items in Grub menu to load the same kernel but into different runlevels. I had configured runlevel 3 (I went into /etc/rc3.d/ and removed the symlink to /etc/init.d/gdm) to be w/o GDM, so that if I had chosen it, my box would not boot into X. How can I achieve the same effect in Lucid?
This is my sons Asus eee pc 1005peb ( have one exactly like it and never happened to me)
The screen flashes on bootup and makes it very hard if not impossible to login and the gnome menu at the top is gone too. I do not know what he did to it. But I am loading meego on it now.
I seem to have the following problem with Ubuntu. I have two PATA drives in my server. The OS is loaded on the first drive which is the master and the server functions fine. This is what I want to do is to have two 120 gig drives in the system and mirror them. When I put the second drive in set to be a slave the bios see's both drives. After the bios shows what is in the system it hangs with the cursor in the upper left hand corner and will not boot beyond that point. If I unplug that second drive it will boot up with no issues.
Not sure if i am correct but I was under the impression from all sorts of posts & videos that 10.04 was supposed to have a fast bootup. I have upgraded from 9.04 jaunty bootup is quite a bit slower than on the old version and is quite tedious is this correct? are there any logs i can upload to see if i have an error some where?
I am frustrated that I do not see the kernels menu anymore, which had such useful tools like the different kernels, the ram checker or the recovery mode kernel, allowing recovery from a botched update, etc. As of 10.10, I don't even get the kernel messages flashing by, all I get is a dumbed-down black screen a l windows, then it boots ubuntu without offering me any of these options.
Have installed Ubuntu 10.10 on a couple of Dell Inspiron 2650 laptops (both 512M memory) and when they run, they're great, but they only successfully boot up maybe 10% of the attempts. Most of the time, the touchpad and keyboard are inoperative, but I recall sometimes the enter key gets me past my user Id to input password. Trying to enter recovery mode isn't any better, but once into recovery, I'll boot up in safe graphics, but it is probably only running because it succeeded in entering recovery, anyways. I have elected to to boot up in safe graphics, but they still both freeze. No error messages, just a frozen background/icons screen.
Ubuntu has searched the hardware and reports there's nothing requiring proprietary drivers installed.
After reading all the other problems posted, I figure my laptops are doing pretty darn good, but it sure would be nice not to set around starting up and shutting down, over and over.
I installed SLIM and rebooted. gdm failed to start so I went to the terminal and ran gdm manually from there. Then i logged in and removed slim package, reinstalled gdm and rebooted. Gdm still fails to start at boot up. When i try to manually start it, i get the following warnings:
Warning: unable to load file 'etc/gdm/custom.conf' Warning: unable to find users: no seat-id found
When it DOES boot, it runs like a champ, and has no issues. However, it tends to freeze up on the boot at the BIOS screen, this issue was around when Windows was on it.
I have managed to install Ubuntu 9.10 on my pc I have Vista installed on one hard drive and ubuntu on another. When I boot up on Ubuntu, the desktop comes up, then after about 30 seconds the pc freezes.
REASON: I want to find out how to improve my boot-up and hibernate-awake time for ubuntu (it is 300% slower as hibernate on windows xp on the same machine)
QUESTION: well my question is concerning the tool dmesg. As I understood from reading the quite brief >>man dmesg this tool will show the messages the kernel put out during the boot-up. true? A typical line on my dmesg output I receive would look like this:
Code: [...] [ 39.632219] i915 0000:00:02.0: LVDS-1: EDID invalid. [ 46.964733] wlan0: authenticate with AP 00:23:08:20:58:6f [ 46.965988] wlan0: authenticated
subquestion:
a) the number in the beginning (is it the time between the two kernel messages?) in the example it wold be about 7 seconds
b) if it is the time in seconds: does it mean the kernel was abusing 7 dseconds for the output of the line? how can I track what causes the delays?
PS: maybe I should post this in a different ubuntuforums subgroup (if so which?) PSS: is there any good webpage (I have not found any yet) on this topic?
When I boot up 9.10, very occasionally, I get a login screen directly after the page with the Ubuntu b&w symbol and before the colour page. It doesn't happen very often but usually when I am showing someone how good and quick Ubuntu is.
