I was considering switching from Ubuntu to Kubuntu. I hesitate because with Ubuntu shifting to it's own Unity, will the Kubuntu project be dropped?
View 4 RepliesI know, minor problem. But on an otherwise clean and fresh looking desktop, that small shift down tends to throw off my chi. Also, it does tend to get in the way a bit, such as obscuring my options button in Chrome, rather than just taking up a bit of unused space on my tabs bar. Wasn't having this issue with 10.04, but started happening immediately after upgrade.Example of what I'm talking about:

I'm looking for the simplest solution that would allow me to run TCP/UDP servers and have a few clients connect to them on localhost emulating various network connections. I'm mainly wondering if I can use something like Linux's netem on Mac OS X (or even better cross-platform Windows/Linux/Mac). Perhaps I can run VirtualBox and a Linux kernel running netem, has anyone had luck with that?[URL]...
I've been receiving a LOT of log cruft ever since I installed my WUSB100V2 (using the rt2870sta community driver from the Linux kernel) and was wondering what it all meant.
Many times when these messages occur it is accompanied by slow network speeds and many DNS queries and outgoing SYNs being dropped. I have searched for documentation for these (error?) messages and have come up empty as far as what they mean or how I can stop them from occurring.
I reside on the opposite side of the building from my WAP. I have taken steps to improve the signal strength, but the signal quality hovers between 50% and 70%, sometimes dropping to 40% for unknown reasons.

My wife would like to wipe her computer and "start over." She's had XP on it for years, but to my delight she asked if I could try Ubuntu and see if it would work. I tried out the Lucid Live CD and everything worked well, except for this one problem.The entire GNOME desktop environment was shifted "downward." I could not see the bottom panel, and the top panel was unusually "tall." I had to click above the "Applications" menu to actually display the drop-down menu.I changed the screen resolution, which fixed the issue. I changed it back to the original setting and everything was normal.When the screen goes blank or to a screensaver, however, the problem returns.I'm not sure I can provide a screenshot as this is all from the Live CD.

Tri-booting. They were installed in the order I listed above. I ran into a few bugs with Kubuntu, so I no longer want to use it. I want to use GParted on a LiveCD to format Kubuntu and expand my Ubuntu home partition to sit on top of Kubuntu's space right now. If I nuke Kubuntu, will Grub still exist with my Ubuntu/XP entries to boot?
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.
I would like to apply KDE on my Kubuntu because the current one blew up. But each time I to sudo get-apt it seems to be fetching from the cloud. Is there a way I can make it to read from my local Kubuntu CD? I have both Ubuntu 10.04 LTS and Kubuntu Live CDs.
I believe the local disk read should be faster to translate than to bite the bytes across thousands of miles over the wire right?
Have Lucid installed on an Acer laptop. With an external keyboard plugged into a USB hub, then into the laptop, I have been losing the first character typed, sometimes. Most of the time it is OK, but it happens many times in an hour. If I am typing right along, no drops. Only the first character I enter is missing. Most of the time it is firefox I am typing into, but not always. My use of this machine is largely online, so probably that is coincidental.
This problem I have never seen before Lucid - I don't remember it in the beta ether, but I didn't run that too much.Versions 9.04 and before were OK (couldn't use 9.10 for other reasons).

I just purchased a shiny new LG 10x BD-ROM Combo drive. I installed it without problems. The rest of my system consists of:
MSI k9a2 platinum mobo
AMD Phenom 9950
3x SATA HDD
nvidia gtx260
That's probably everything pertinent. I have the SATA HDDs installed on SATA ports 1, 3, 4 (not the promise slots, 5 & 6), and the BD-ROM installed on SATA 2. I don't think that's an issue, though. I did replace a working sony opiartic (sp?) DVD-RW, so I don't suspect any cable issues (for that and for other reasons).
note: "restart" = "reboot via restart", as opposed to power down & turn back on.
1. I turn on the power. BIOS posts that it sees the BD-ROM in the SATA 2 spot.
2. I boot into Ubuntu 9.10 (updated with the latest x.20 kernel). It does take a little longer than usual to load between the grub menu and the login.
3. After login, the device shows up as cdrom0 in the "Places" menu. Clicking on it returns an error whether a disc is in the drive or not. At this point, however, the open/close button on the drive no longer works. Its as if it's lost all power or connection or something.
4. When I restart, BIOS hangs a while while posting. It shows only devices on SATA ports 1, 3, & 4. It's as if the BD-ROM doesn't exist anymore.
[code]...
lspci and lspci -vvnn show nothing... well, technically they show everything BUT the drive. I'm planning on purchasing a second BD-ROM (different manufacturer, if I can help it), to test later, but I don't have high hopes. It could be a motherboard issue, I suppose, but updating the BIOS from 1.4 to the latest version (1.9) solved nothing. I don't suspect it's the hardware, though, since it works fine in Win7. I imagine that the culprit is linux/ubuntu, and I need some help figuring out if this is a fixable problem. I've been really, really happy with Ubuntu and linux in general. Ubuntu is my primary OS, with Win7 as my backup in case of emergencies, but I'm seriously considering wiping linux & using Win7 exclusively altogether with this severe hardware issue.
I've been using my current laptop since Ubuntu Edgy Eft and, since then, I never had any problem with wireless ( Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02) ) Since I upgraded to Lucid, my connection is dropped approximately every 3-4 minutes for 10s. Network-manager doesn't show anything but it is well visible with the netspeed applet that shows a warning sign "No connection" instead of the speed.This is very annoying and frustrating. I recall having seen the same issue in an blog article where the author was talking about his upgrade to lucid. It was just one line and I didn't care a lot at the time and cannot find the article back.
Is there anyone having heard about a possible issue ? (I've upgraded from Karmic when Lucid was still in Beta, so it might be the cause).
I was living peacefully with 10.04, till I upgraded to 10.10.

Booting is not graphical anymore, but rather a low-resolution `Ubuntu 10.10' big-font text.Can any1 help me install the correct ATI driver (if any) and get rid of the corrupted fglrx synaptic driver?
View 6 Replies View RelatedUbuntu 10.10, Firefox 3.6.13, IceTea6 ext, Greasemonkey, Firebug, FlashBug.. Everything was going just great, then poof. Firefox seems to have lost the ability to interpret java and javascript extensions. It's strange, I have a javascript extension that I've used a lot in the last 2 to 3 months. One night, was using- refreshed, gone.
Script was still there in GreaseMonkey, with all it's pointers to the web presence. I have Google Chrome with the same extension and it stiill works fine. Thought maybe it might be an install problem, so uninstalled/reinstalled Greasemonkey and the script//no change. Uninstalled and reinstalled Firefox and extensions//no change.
I used Firebug to inspect element on a familiar web page where I inserted a table with imbedded javascript. doesn't execute any of the onclick processes on it. This table "is" something that I have inserted on that same page previously with no problems and it executed those same onclick processes fine.
Which leads me to believe that somehow, in the past few weeks, I somehow lost the abilty to process java and javascript. Could this be to soem recent updates or upstream changes? Note-- I do have Eclipse IDE, JavaBeans IDE and Monkey Studio IDE installed on this instance of Ubuntu. I've stayed with Ubuntu's flavor of the OpenJDK, instead of going to Sun's JRE in an attempt to stay open to future shifts and directions.
I'm working right now with ubuntu 11.04 on my asus ul30vt-x1, my wireless n network is working on a linksys e3000 router, my issue is basically with long file transfers. When the issue started i was reaching speeds of 100 Mbps through my wireless network even when I'm connected at 150 Mbps. However when at this speed, I don't know why, the connection is dropped after some minutes or even seconds. I made some testing on windows, I'm reaching 70 Mbps there and no problem at all with dropping the connection.
So my conclusion is that for some reason the linux driver, in my case, is not able to handle such speed of 100 Mbps. I know that a wireless network will have a throughput of aprox 60% the wireless speed. Right now im trying to apply traffic shapping to my transfers so i can get 70 to 80 Mbps, its being working so far.
I just dropped my laptop while it was on. It is a dual boot vista and Ubuntu machine (9.04) and Ubuntu was running at the time. The machine didn't go down and after I got done using it I shut it down normally. Now it will not come back up because grub is saying there is something wrong with the disk geometry. It did give me a command line, I forgot the exact error message but I can look it up if needed.
I tried plugging the hard drive into a different machine under a live cd but everything was in the lost and found folder (80 GB) and the folder was unreadable. I backed up the windows partition successfully using windows explorer and now have been looking at testdisk and Stellar Phoenix Linux Data Recovery ($80) for the Linux partition. I don't know if it is ext3 or ext4, I may have bumped it up to ext4 from the default ext3 during the install. Also a few files on the windows partition were unreadable, so the disk definitely has some physical damage. I'm getting a new one along with a back up system for sure after all this is over.
I got tired of figuring out testdisk so I let the paid app run its free test overnight to see if I could recovery anything before I bought it, but it got hung up on a sector halfway through.
Going forward I think I will try Photorec next and then testdisk again if that doesn't work. Does Photorec get almost all the normal office (doc xls), music (mp3) and video files (mp4) not just pictures?
I'm getting dropped frames from both Digital8 & MiniDV camcorders using Kino. MyCPU doesn't seem to be spiking. I've made sure compiz is disabled and no memory/cpu hungry apps are running. I'm using SATA drives so DMA shouldn't be the issue.

One of our RHEL 5.3 servers has trouble about 30% of the time with TCP-based communications, but it does not seem to be firewall issues. From another computer on the same switch, you can SSH to the server sometimes and other times the SSH command will just hang. When it hangs, you can often just Ctrl+C and try it again and it works. Same with HTTP connections. You'll get part of a web page and then FireFox will just hang waiting for the rest and eventually time out. Same goes for communication initiated FROM the server. SSH'ing from the server to any outside server or connecting to any web site works sometimes, but most times not. iptables if off. No other firewalls are running. Tcpdump shows communication gets so far and then stops. It does not matter whether tou run tcpdump on that server or the client connecting to it. Either way you see the connection stops working. MEANWHILE, pinging with small or large packets works flawlessly. 10,000 packets, zero drops.

I'm using iptables to do NAT forwarding and everything works great except that, occasionally, connections seem to break. Ssh connections close with "Connection reset by peer" and HTTP connections just stall out.I believe this has to do with the firewall's internal network interface occasionally dropping packets.

We do NOT support samba on our Unbuntu servers but still zillions of windows machines are constantly trying to connect on the SMB ports. I've added a rule that drops access to destination ports 137-138 and that seems to work. But it creates many many log entries documenting that the packet has been dropped. I've been researching and cannot come up with a way to suppress logging for these drops.
