Was just wondering if it was safe to run devices off of an unpowered USB-hub, unfortunately I do audio production and when the DC-adapter is connected I get horrible alternating hissing noises through the sound system. Was just wondering if it would be safe to connect an external mouse, keyboard and a self-powered printer to the usb-hub without drawing too much current and wrecking the system.
View 6 RepliesI'm working on a server and noticed that the to RAID5 setup is showing 4 Raid devices but only 3 Total devices. It's on a fully updated CentOS 5 system that only has three SATA drives, as it can not hold anymore. I've done some researching but am unable to remove the fourth device, which is listed as removed. The full output of `mdadm -D /dev/md2` can be see below. I've never run into this situation before.Anyone have any pointers on how I can reduced the Raid Devices from 4 to 3? I have tried
mdadm /dev/md2 -r failed
mdadm /dev/md2 -r detached
but neither work and since there is no block device listed I'm not quite sure how to get things back in sync so it's only seeing the three drives.

View 3 Replies View RelatedI am using 10.04 right now and the other time i tried upgrading to 10.10 beta version or alpha version it turned out to be a complete disaster cause it just wouldnt boot into the GUI no matter what. People say it was due to my ATI driver. Now since its a stable release, I want to make this install as perfect as possible so i dont have to reformat everything like i did last time.
Should i copy my whole filesystem into a external drive? In the event it doesnt work , i can just replace the files with the files on the external drive rite?
I'd like to install apache so I can tinker around with php a bit. I read a thread on how to set everything up, and it ended with a chap mentioning that it's important to take security measures while running apache. I haven't "gone out of my way" to make my Ubuntu install any more secure than it comes out-of-the-box. I keep my system updated via Update Manager's automatic updates, but that's it.
So my question is, am I ok to go ahead and plod through some php tutorials using apache to do the server-side stuff? what I would do to keep things safe if I were using a Windows machine?
I read some of the thing under thread about ubuntu not working after update to 9.10, mainly connected with nvidia etc. This all seems rather complex for someone with only small experience. The Q is : is it safe today (bugs fixed?) to update from 9.04 to 9.10 simply via the update manager? Or will I have definitely no running system then and will need lot of special work to be done on drivers etc? My system is a dell dimension 4550, nvidia GeForce4 Ti4200. Or is the upgrade to 9.10 to dangerous still?
View 9 Replies View RelatedAbout 3-4 weeks ago, I tried upgrading from 9.10 to 10.04 several times, using all of the methods. However, every single one of them had a bug; a black screen, completely blank. I saw other people had this problem and did everything others suggested, but yet I still got that black screen. So I decided to wait a few weeks and see if most of the bugs have been fixed. So is it safe to upgrade now?

View 4 Replies View RelatedFirst let me say sorry if this is in the wrong thread. I am a bit of a noob when it comes to linux. I was trying to figure out how to get an external monitor as my primary monitor on my laptop when i made a change that cause the desktop environment to keep logging me out. I got it into safe mode and resolved the issue but i have my account set to not ask for a password on login and it keeps booting to safe mode now. I have tried logging out and typing my username to get the option to select the normal desktop but as soon as i enter my username it boots bake in as safe mode. The option to require a password on login is not working in this mode. Anyone know how I can get this corrected?
View 1 Replies View RelatedSo I upgraded Ubuntu and was greeted by Unity. I was unsure of it at first and figured I would give it a shot. It has failed miserably in almost every way aside from looking nice in some instances. It's slow, clunky, and was a total wreck to my efficient use of the computer. But they can't all be winners I suppose. I can see where it would be useful (since it seems more finger-friendly) on a tablet device, but I'm using a standard notebook, not a tablet.
That being said, I switched back to what is now "Ubuntu (Classic)" and have put things happily back on track. However, since I have no intentions of ever bothering with Unity again, I want to remove it - it's just wasting space. My questions are, would this be safe? Are Unity and Ubuntu entwined to the point where doing so would make future updating/upgrading a problem? If it is a problem for the future, I feel it would be easier to just change distros (Mint, OpenSUSE, or just Kubuntu) - any recommendations?
I have UBUNTU 11:04 and prefer the display given by " SAFE MODE" - is there a way that I can lock to ensure that Ubuntu always boots up in safe Mode.Save me having to remember to change the preferences every time I reboot. Alternatively can I change the display to be equal to that given in Safe Mode.

I tried to go into safe mode to clean the old drivers out with Driver Sweeper, but when I boot I get a menu asking me which disk I want to boot from (Asus motherboard P5Q <green>) and I have gotten this before and I usuall just hit esc to use default drive and start pressing F8 repeatedly but it just goes to GRUB dual boot menu and there's no safe mode for windows listed. I also tried pressing F5 as that used to be the safe mode command, but it does nothing and goes straight to GRUB.
View 3 Replies View RelatedWhen I first started to install Ubuntu to my system, I got an error that told me Ubuntu was not successfully installed, so I restarted my computer and tried again. That time it works, and I'm thoroughly enjoying the OS. I noticed that when I start up my computer and I have the OS boot list, Ubuntu and Ubuntu safe mode are listed twice. How do I remove the 2nd one, and is it still installed on my other partition even though it said failed?

View 6 Replies View RelatedI currently have a nice HTPC setup that has been upgraded from distribution to distribution since 8.xx all the way up to 9.10 now. I just moved to a new place and it feels like the right time to do a fresh install of 10.04 into the HTPC. The problem is that I have a RAID 5 array in the system that has all my pictures, videos, music, etc. This OS is installed in a separate drive that is not part of the RAID array (I have 4 drives in the system, 3 in the array, 1 for the OS). what is the general process I should follow to do:
1. a fresh install of 10.04
2. do #1 while at the same time not losing my array (don't think I would anyway).
3. what to do after install to get the array back up and running and mounted.
