Ubuntu :: Increasing Maximum Number Of Applications In Browser?
Dec 28, 2010
I just installed maverick on my son's netbook, and so far we like the new unity interface. The main issue is that there seems to be a maximum number of apps that can be listed under any particular category in the applications browser. So for instance when he goes to his "Games" category, it only lists applications up through S (he has a lot of games installed).
So far I haven't found a settings panel for unity. There has to be a way to bump up the maximum.
How many users is it possible to set on Ubuntu 10.10? I have an Edubuntu LTSP system for a school (10 clients) and I wish to setup an user for each student/teacher (about 200).
In the last week or so, I've frequently been running out of X server client connection slots and getting "Maximum number of clients reached" errors. For example, I'm getting it right now and I'm running 3 pterms, Chrome, and Thunderbird; I've even killed my panel. 'xwininfo -root -children' produces what seems to be an absurd number of X clients (150-ish, when it's able to make a connection), even immediately after Gnome/Xfce startup.
It doesn't take long. A day at most. I've had this system up and running for months, and this just started happening. I did install some X development libraries (x11proto-core-dev, libmotif-dev, x11proto-print-dev, and x11proto-xext-dev plus their dependencies) about two weeks ago, but this problem has not been happening that long. I've installed other packages, but nothing that would seem to have any relation to this problem. I've logged out and in, rebooted, and changed from Gnome to Xfce, and none of the changes helped.
I was wondering what is the maximum number of partition on an GPT-partitionned drive under Linux. The GPT partition table can contain up to 128 partitions, but the device nodes for /dev/sda? (as described here, block device of major number 8) only allow /dev/sda1 up to /dev/sda15. Does that means that there cannot be more that 15 partitions on a drive, even on a GPT-partitionned drive?
Is there a limit to the number of files ext3 can support?
Reason I'm asking is because on one of my internal drives, I have around 750,000 files. The drive is 500Gb and currently using 150Gb... I noticed recently that when I try to copy a new directory or file, the transfer rate is extremely slow at times. It is sataII and sometimes it gets as low as 500kb/s (yes, kb!)
Would somebody please shed some light?
I noticed it might be related to the process gvfsd-metadata
I really need to know this for a linux server, but since it also applies to client OSes, I figured the question should be posed here instead of server fault.
I would like to ask you if there is any maximum allowed number of files per folder in linux (without risking it to lose everything). I am using openuse 11.4 with latest kde (4.6?).
I am trying something fast and dirty and it might be that one folder will contain like 10^6 files.
Is there is anything I should be warned about that?
I have a 32-bit Linux server with an ext3 file system. Is there any kind of upper-limit to the number of hard links I am allowed to use? (Per inode...? Per directory...? Per filesystem...?) And (just out of curiosity) would this be any different if I had a 64-bit machine or a different file system?
I have done nothing with the system, but starting this morning, i experienced a strange condition on my desktop. I'm unable to open any applications at all. It will close instantly.
When i tried to run from terminal, it will give me an error like this:
Quote:
I checked using
Code:
And i got around 234 which is too much that it takes almost all of the open files allowed. Logging out to text and brings back X will solve the problem, but it's only a temporary solution until X opens more sockets again. I'm running -Current (32 bit)
It seems that there's a hackish solution in here: [url]. Dunno whether it's a nice solution or not, but i'm willing to try it.
I am created one udp socket. i want to send the data(bytes) to another PC.i need to send 614400 bytes of data. while sending it saying error like" message is too long ". so what is the maximum possible data can i send from a socket?
While searching for the maximum numbers of CPUs supported by CentOS 5 x86_64 I found the following page: [URL]. The question I have regarding the specified information ("64/255" logical CPUs) is, which number means what. Does this mean 64 real CPUs with a maximum of 255 cores/hyperthreaded CPUs or something similar or totally different?
What is the maximum number of virtual network interfaces possible?I would like to create around 300 or so. This is needed to simulate a 300 node network.
I tried ubuntu for a few weeks, but I couldn't get the nvidia drivers to work, I tried everything. So, I got sick of that, and went to download OpenSuse, which seems to be even nicer (..... ) I downloaded the 11.1 liveCD (gnome) from here. I nicley got the welcome screen, and the option screen (liveCD, check errors etc.). I chose LiveCD and it started booting, I got the splash screen with the loading bar, and after it completely loaded, the screen turns black with a lot of messages and at the end:
Code: GdmLocalDisplayFactory: Maximum number of X display failures reached: Check X server log for errors. Great, I hoped for better luck after Ubuntu.. My sys. specs: Asus F3Sc 32bit Intel CentrinoDuo

I with one problem to open files on terminal. By example, I open the thunar on terminal, see the error:
gustavo@universe /media/montagem $ thunar (process:7902): Gtk-WARNING **: Locale not supported by C library. Using the fallback 'C' locale. Maximum number of clients reachedThunar: Cannot open display: gustavo@universe /media/montagem $ ^C
Ever since upgrading to Fedora 14, my system has been almost unusable. I can only have a few windows of anything open before I start getting messages about:
Maximum number of clients reachedMaximum number of clients reachedMaximum number of clients reachedMaximum number of clients reachedxwininfo: unable to open display ':0.0'
I am unable to open any new windows then and lots of programs crash.
what the maximum number of logical volumes is for a volume group in LVM ? Is there any known performance hit for creating a large number of small logical volumes vs a small number of large volumes ?
I am using Fedora 12 and i have enable XDMCP i have boot client with dhcp all is going well but when remote user logout than remote client display XDMCP: fatal error: Session declined Maximum number of open sessions. and after that i have reboot Fedora 12 server than it will work but after logout it will again create same problem.
I'm trying to extract the sender id from a fairly large number of files and am having trouble assigning variables from a file. Here is what I have so far, (which is fairly kludgy I know, but it's been some years since I've done any scripting or programming, and I find that I have lost the knack to a large degree).
I bought a netbook (VPC) which is basic netbook with limited features. It has a basic version of Linux (Linux 2.6.24 platform). My instruction booklet says it does not support Flash (player): Flash - The current browser does not support any Flash players. This will prevent viewing some web pages. Certain major websites have a simplified version on the server which will load up. When I try to play games in flash, it does not work either. Browsing on the web also is very limited, I only see mobile (cell phone) versions? (the instruction booklet does state this though) I cannot even put favorites? Is there a way that I can get Flash installed or a better browser? So I can play games that are on Facebook, etc.? and view websites like a "normal" human being should be viewing them on the web?
This is what I figured out so far: Wi-Fi Onboard USB and Ethernet ports An SD reader 7″ TFT display with an 800X480 resolution 2GB of internal storage 100 MHz processor
Linux with preloaded programs such as internet browser, spreadsheet, word processor, a media player for movies, music and pictures, e-book reader, dictionary, calendar, PDF reader, email, chat, calculator, file manager.
I'm trying to figure out if it's possible to configure apache or any other linux http server, to allow the visiting user to start applications installed locally on the http server and get the GUI of that application displayed in a java applet (or any other similar solution). In short, I'm looking for an alternative solution to proprietary technologies such as Citrix and Microsoft Remote Access Gateway.
In the left pane of Nautilus File Browser, I can only display directory and file names. I don't have the button at the top of the pane which allows me to select an alternate view such as Tree view.
My family have three Linux operated ACER ONE netbooks, all of them need the new Firefox 3.6 download as the old format wont be supported supposedly by ..... etc. I have downloaded the SOFTWARE but cant get it to run, the Firefox explanation mentions lots of files etc that are cant access, nor can I excecute any files once they have been extracted. The same happens with any software but Iv ignored it till now, not having a "modern" browser will make things difficult. I need it explaining simply. On another subject can anyone use facebook chat on Linux
I'm going to try Firefox 4 in Fedora 13. I would like to do it neatly, meaning it appears as an option in the "System" -> "Preferences" -> "Preferred Applications" settings for all users as "Firefox 4". Moreover, I'd like it not to ever ask to make itself the default browser when it's first run.
