Ubuntu Installation :: Clever Coding In 10.04 / Get It Back To Where It Is Not So Bleeding Edge And Broken?
Oct 10, 2010
I hesitated on the title, generally can solve problems w/o this (20+ year *nix/linux experience).
hardware Dell 1505, ATI X1400 (nVidia went south replaced with ATI, used at this stage of life for this laptop).Acer x221w external monitor.
Recently upgraded to 10.04 (should have waited, but hadn't upgraded in a long time).
No real fixes found for the ati X1400 in searches (fixed it on 9.04 and 9.10).
So to troubleshoot, wanted to go to console mode, and start X manually and hopefully debug the config to get the thing working.
So, I get ready to take it down off of X only to find, there are no more consoles???
To work this out and to even come to an end result, when X does not work, you need a console to debug it. There is code in /etc/init.d/console-screen.sh for starting consoles...
Yet they do not start, notices some comments about doing it 'clever' in there, all I can say is 'clever' is more risky than workable, it worked before, why change it? It did not make it better, it made it harder, so now, to get it to work, I have to go debug someone else's 'clever' code? BTW, there are 'getty' running - but still no console.
Not so clever... We need a fix to get (at least at this level), the consoles running, so, where are you 'clever coder', tell us how to turn them back on.
Why in /etc/init/tty*.conf do they not start?
I really find it hard to say anything critical to something that is free, in general, I will not even comment, but just go ahead and find the fix myself, But to even address this, we (IMO) need pretty much a fix for the broken console access, before we can even address X in certain configurations.
A long time user of RH, even back to Yygdrasil, Soft Landing days, I was VERY impressed with ubuntu over the others for a desktop (got it on the Dell), but now, at 10.04, it has become cumbersome and broken.
It is a good product, but we need to get it back to where it is not so bleeding edge and broken.
Some searches seemed to indicate that it's been awhile since there's been a build thread, so I thought I'd start one. I'm looking to replace a six-year old machine (Athlon XP 3200+ processor (introduced in 2003), integrated graphics with no dedicated graphics card). I'm rocking Windows XP Home Edition (32 bit).
I'm not a "computer hobbyist," far from it. I use my machine mainly for browsing, word processing, and business (QuickBooks and Turbo Tax). It is a tool. I don't really enjoy fiddling around with computers. My current machine is now barely able to support a good research session on the 'Net anymore, the little processor seemingly gagging on the heavy flash content you see everywhere nowadays, the 2GB (the most she'll take) of RAM easily filled.
I'm planning some rough travel international motorcycle trips (see my motorcycle build thread here (don't worry about registering on this motorcycle forum.....they are good folks and I've never gotten any spam from them) and purchased, a while back, an Asus eee PC 901 with the OEM Xandros (a bastardized offshoot of Etch) loaded to use with those trips. From learning that OS, I saw for myself the benefits of Linux (vs. Windows). Of all the distros, Debian is the most attractive to me (even though I'm currently rocking Puppeee (new version) on the 901.....it makes that little machine zoooooom!) as I really like the package management system, the logic, and the stability. I also like the feeling of personal responsibility that comes with Debian.
So, back to the build. I'm currently planning on it being a pure Debian machine. I'm ready to move on from Windows, for reasons I don't have to explain here. I stated that I don't particularly care to "play" with computers, but I'm willing to put in some front end labor in order to enjoy a long-term, low-maintenance relationship with my new machine. With that philosophy in mind, I'm looking to build a machine that will serve my simple needs for ten years(!) So, since the costs will be spread out so far, I'm ready to drop some serious (for me) coin on this project in order to avoid having to go through what is, for me, a rather painful process of research again any time soon.
I have AMD Athlon 3500+ (x86_64) CPU and I am okay with the Ubuntu package maintainer's kernel version (as of now it is 2.6.35-24-generic). What will I gain if I update to latest stable kernel (2.6.36.2)? A fraction of performance?
I'm trying to compile the bleeding-edge compat-wireless because I know there are some ath9k fixes in it because I use in on my Debian and Ubuntu machines; however, when I try and run make, I receive this error:
Code: make: *** /lib/modules/2.6.38.8-35.fc15.i686/build: No such file or directory. Stop. make: *** [modules] Error 2
was waiting to install the "cutting edge" Fedora 11 and I did it immediately after its official release. The 1st day I installed the Fedora 11 ...... the system declared a kernel problem. I don't know what was its problem. Anyway I continued with this OS and I was taken day by day all the official updates. I could see everyday that the system was not stable enough. Problems - problems - problems..... Sometimes there was a critical ext4 nfs error but my hard disk is new and ok. Fedora 11 was the only OS into this hard disk. So....I installed the "bleeding edge" Fedora 11 once again - I took again all the official updates and I tried again. Nothing better. Today Iam sure that the ext4 file system is the main problem here, it is quick but not secure enough. That is my conclusion. Yesterday Okt 11 2009 I installed again the Fedora 10 OS with the old ext3 file system and Iam so good again.
I have an HP with an all-in-one clickpad that does not work properly with ubuntu since it's mostly software based. I have tried many workarounds to fix this problem with little success. One of those workarounds got rid of the touchpad tab in the mouse setting window. Can I get this back to disable tap-to-click and enable edge scrolling?
I have a script which basically does many tasks and most of them can run in parallel. The server it runs on has 4 cores, so I changed parts of it to a makefile, and then run them with "make -j 4" which helps a lot. But looking at "top" while it runs, I see it could be improved. Sometimes tasks wait for other servers, so a higher -j value would help. And sometimes multiple tasks are waiting on the same disk, then I think a lower -j value would be better.
The kernel is fairly good at sharing CPU time among the cores, but resources like memory and disks are not shared very well. As an experiment, I tried compiling the kernel with "make -j" with no number. It didn't go very well.
So I wondered if anybody know of a better tool for things like this. I think it should be possible to write something that could change the -j value while it runs.For example:
- Start as many tasks in the background as there are cores. When tasks finish, start another one until done. - After a little while, check CPU and memory usage to decide if more tasks could run in parallel. Or maybe less? - If different tasks iowait a lot, check if they wait on the same disk. If so, renice/ionice/suspend some of them. In these situations I think it's better to have them run one after another. - Other ideas?
I thought of making a script like that, but I doubt I'm the first one with that problem. Also, there are probably lots of things I haven't thought of.
I upgraded directly from 10.04 (Lucid), and now have TWO problems. I thought I was upgrading to 10.10. Surprise! I now have 11.04, and the following Web site is broken:
I am running Ubuntu 10.04 amd64. So I have just returned from a week vacation to see that my / is full. When I had left, the ~80G partition was only consuming around 40G of space. I feel like this is a bug and i haven't tried a custom kernel yet to see if it is kernel level. Here is all the good information though to help debug:
Code: mount # mount /dev/mapper/pdc_cfefedbci3 on / type ext4 (rw,noatime,user_xattr,errors=remount-ro) proc on /proc type proc (rw,noexec,nosuid,nodev)
[Code].....
I am using a fakeraid with dm-raid on a raid0 for my /dev/mapper discs. I just wonder if anyone else is getting this error or if it is a problem with ext4.
bouncing icon and spinning icon in toolbar for 10-20 seconds, then nothing. Is there a special log file to be found for mozilla errors? (couldn't find anything useful in or near /var/log/messages or warnings all dependencies of associated programmes seem to fulfil dependencies, but obviously something isn't right. Does anyone else have the same problem?
I had a hell of a time getting 10.04 to work, because I only have a Logitech Dinovo Edge keyboard, and it stopped working after I upgraded. After grub, I'd get to the login screen, and the keyboard wouldn't do anything.
First, I dug up a mouse that did work. Then I logged in by clicking the Human Accessibility icon on the login screen. Somewhere in there, I was able to bring up an on screen keyboard. With the on screen keyboard, I could now login. Under system>preferences>bluetooth, I was able to, after some fiddling and plugging and unplugging, get the keyboard paired to the bluetooth dongle. Anyway, it seems pretty obvious now that my original bluetooth pairing was lost with the 10.04 upgrade, and I just needed to re-pair. I don't remember having such problems on previous upgrades, though.
I tried to install Debian 8.1 on Lenovo Edge 125, but on stage ''detecting network hardware' of install process my laptop stopped and froze, so I don't know what to do. (Previously I've installed Debian 6 or 7 on this laptop and every thing was OK).
I'm having problem in installing debian 7.5.0 on Dell Power Edge R 470 1U Rack Server ( Not Sure If am using RAID 1 ) whereby the hard drive is not detected. This server is running 2 Proc/2x1.2 SAS HDD . The installation went ok until i reached into partition section whereby the drives is not there to be selected , throwing an error " No disk drive detected , Driver needed fro your disk drive "
I've tried to use debian-7.8.0-amd64-DVD-1.iso
My server details: Dell Power Edge R 470 32GB RAM 2 x 1.2 TB SAS HDD
I've been trying to fix this problem for quite a few days now and have done a lot of searching on these forums, Linux Mint Forums and some others Google lead me to and have has some success, but am now stuck.I have posted a thread on this same topic on the Linux Mint Forums, but have had no success (if you want check it out at:URL...Originally I received error messages when trying to update involving certain repositories which couldn't be accessed (because they either didn't exist or had been moved) and I hunted these down and changed or removed them.
I have done much searching, etc. and cannot find any broken packages. I have tried many many different commands which have mostly done nothing.I seem to be in a similar boat to this person: URL...
I am writing a script that will ping a server and then do a command if it gets a ping that is less than 100ms or more than 100ms. Basically, I need to have a variable for the ms.
Here is an example script.
Code:
Now, all I need to do is get a variable from the ping. I know I can do this:
Code:
But that just sets the whole line, I only want the ping, without "ms" at the end.
So basically, if I ping 25.25.25.25 and get 43.872 ms I want $pingms to equal 43.872.
Also, how can I do this with free, for example:
Code:
I want $ramavail to equal the amount available and I want $ramtotal to equal the total amount.
I recently downloaded Metasploit framework for ubuntu but i got an error which says could not open <file location>
Saying gedit has not been able to detect the character coding. Check that you are not trying to open a binary file.Select a character coding from the menu and try again
Zen-coding is a great gedit plugin for html & css development.I download the files and unpack them into ~/.gnome2/gedit/plugins/.After open gedit I can't find zencoding in the Gedit Preference.
I'm doing some shell scripting in nano, but code is much simpler to read when is color coded.... is there a terminal editor that supports color coding?
Yes it's me again, about to ask a foolish question.I've ran man on this commands, but they don't make any reference to their color, nor is it mentioned in the Bible. As I go through such as /sbin what does the color of the commands mean, like arch is green, awk is blue, and then there is those that have a red background such as cgexec?Then I go into /etc and then there's yum.repos.d there is no man for it, so I typed it in and got "command not found", so then I went in SU mode and "vi yum.repos.d and I get "yum.repos.d" is a directory,No such file or directory. So just what is yum.repos.d, I thought this is where I add more repositories.
Can I get someone that is using Ubuntu/Lucid and Firefox as browser to run a test for me? Can you go to this website and then type the either the word "HIGH" or the word "LOW" in the search box and then tell me if you get the same bunch of program error codings that I get when I try this ? Want to see if this is a problem with just my computer setup or with the websites programming. [URL].
I am trying to see how programs for cdroms use reed-solomon coding. I looked in the site lxr.linux.no , but couldnt get anything there, too much details present.
In Fedora, I used the ls -l command to see the directory listing. But I noticed that while all .c files were being shown in green , there was one .c file which was being shown in black.How can two files having the same extension be executable /normal?
What sort of libraries can i use for coding of sniffer program for windows and linux? The sniffer that i want to code is for capturing the list of connected clients to AP wirelessly. I do know that the wireless NIC needs to be in 'monitor' mode in both windows and linux.
I'm working on RHEL5 dealing with AS (ActionScript) files in Linux GVIM Editor but everything is in blue color. Can i set color coding for my keywords?
I've been a PHP developer for about 6 years now - the last two years I have been pretty inactive though. Just recently though, I have been reading resources on all the different programming patterns (Factory, Singleton, Registry, Observer, MVC, etc) to try and get my head around good programming techniques. For myself though I find that I can only truly understand how these methods work when I am forced to do them myself.I have a large project I am doing at my workplace (me only) that involves building a very complex PHP application.
I would like to know your professional opinion; should I spend the extra time to program this PHP application myself and really, properly learn all these different programming patterns? Or, should I just build on top of a PHP framework like the Zend Framework for speed's sake (and flexibility/features)?
I have found understanding exactly how the Zend Framework works hard, just because I haven't been exposed to using these programming patterns myself. I hate that - I want to fully understand exactly what is happening in my application and know exactly how each part relates to others.
