Ubuntu :: Are 64 Bit Lucid Disks Suitable For Intel I5 Processors?
Jun 1, 2010
Are the 64 bit Lucid disks suitable for Intel i5 processors? The AMD64 part is making me think not.I already have the 32 bit version running very nicely - should I have gone 64 bit though? What are the advantages/ disadvantages, and why does it say not recommended for daily use next to the 64 bit download? As far as I understand you can run 32 bit binaries without problems on a 64 bit install.
In Ubuntu Lucid 10.04, when I click a disk in the left panel of Nautilus for the first time, the disks are getting mounted without asking a root password. This was not in the case for the previous versions of Ubuntu. how can I turn this feature on in Lucid.
Lucid has been good to be so far, except for the fact that my screen flickers occasionally (I'd say once or twice every 30 minutes) I'm using an ASUS laptop with an INTEL GMA 4500MHD (It's this laptop. I read a bug report about the xserver-xorg-video-intel, but the issue was much more severe and marked as solved before Lucid was released.
1. Sometimes when I try to shutdown my computer the display becomes filled with pixels of different colors as shown in the image (The problem is very random so I was not able to take a photo, I tried to recreate the effect using GIMP). Then the display turns off (Analog power saving mode) But my system never turns off.
2. While working on my computer the display sometimes goes kaput and blinks as in the second image. It stops responding completely I am not even able to go to terminal (Ctrl + Alt + F1). Leaving me with no option but to use the reset button. Causing me to loose all the work in progress.
3. Firefox responds very slowly upon closing it takes 5-6 seconds for the window to close.
PS:- KMS is also disabled in my system. Enabling it didn't improve stability. and here is the output of my videocard (lshw)
I honestly have no clue how this happened, but compiz now refuses to start. I discovered that somehow GLX had been uninstalled and replaced by SWX (the software rasterizer - this gives Brian Paul as the OpenGL/GLX server vendor strings). Reinstalled GLX, currently have Direct Rendering and the proper vendor strings (SGI and Tungsten, I believe).Still nothing. OpenGL seems to be working fine, as Nexuiz runs pretty well.I tried running compiz --replace from the terminal to get any errors, but it just spits out "Falling back to default window manager", without so much as a hex code to tell me why--------Update---------Ran compiz --debug --replace to see if I could get anything else. It gives the following:Quote:taintsauce@the-****ing-fury:~$ compiz --replace --debugcompiz (core) - Debug: Could not stat() file /home/taintsauce/.compiz/plugins/libcore.so : No such file or directorycompiz (core) - Debug: Could not stat() file /usr/lib/c
I'm still searching for a propiertary driver for my netbook (Asus EEE 901 with an Intel GMA950 graphic card). Display controller: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller (rev 03)
Does someone know how to install a driver with 3D-support? Should I use a driver from[URL].. I had no problems at Karmic, because the driver was found at "Hardware Drivers". Lucid doesn't show me any driver there. Is there any correlation between the big intel-graphic issues and my 'problem'?
New to Ubuntu. I've read all I can about the current mic issues with the Lucid 10.04 release. There does not seem to be any specific threads dealing with the GM45 chipset. I've had sound out of speakers on fresh install, and have done every single line addition (individually) suggested with:
I have an Intel DX58SO motherboard with the ALC889 onboard sound, running kubuntu 10.04, and I am not getting analog sound. Strangely, spdif is working great, but I need analog to work, too. I've been in alsamixer, nothing is muted. That's the extent of my troubleshooting knowledge for sound issues.
I've downloaded 10.04 desktop (twice) and server (once). The server install will boot fine, but the desktop install goes to a blank screen (and the monitor goes to sleep) after leaving the Live CD menu (Run from CD, Install, Check Files, Boot 1st HD, etc.).My first try at downloading the desktop CD was using BitTorrent, and appeared to go OK. Burned the .iso image, booted, and when I got the blank screen I suspected the Intel D101GGC motherboard using the Radeon Xpress 200 chipset had problemsI tried adding boot options (F6) such as vga=711 and xforcevesa and text. No joyOthers seemed to have gotten a successful install so I turned may attention to the CD, suspecting it was a bad download/burn, and downloaded 10.04 desktop again from mirror.pnl.gov/releases/. The two .iso images compared equal, so I used a different CD burner, with different media and got CDs which compare identical. Both CDs fail. Then I downloaded the server CD from PNL and it ran! I could select the "test CD" function, which ran in a text mode and said the server CD was OK. I started the install, and it went OK.
Q3: The lshwoutput shows two displays, display:0 and display:1. Can someone tell me why two and how to make use of both of these? NOTE -- The existing forum entries are mostly from April 2009 or talk about Compiz issues. While Compiz will squeeze video hardware pretty well, I use a tablet-PC and so far, Compiz features do not play well with tablet features.
A few months back, my Lenovo IdeaPad Y510 stopped connecting to my wireless network after coming out of Suspend (it had worked fine previously). Wireless networking is simply disabled, and I have to reboot in order to get it back. I tried upgrading my OS from Intrepid all the way to Lucid, but the problem persisted. I also tried changing my 00sleep_module as suggested in this thread, but to no avail.
I have/had a PC with several hard drives, and a mix of ubuntu and windows on multi boot.The old boot drive died screaming, and I need to start again. (But my data is safe! yay!)
Is there anything special about which drive can be the main drive to start booting from? Or to put it another way, can I install to any of the other 3 and expect it to work, or do I need to switch them around so a different drive is on the connections for the recently dead one?
I have servers which contain SATA disks and SAS disks. I was testing the speed of writing on these servers and I recognized that SAS 10.000 disks much more slowly than the SATA 7200. What do you think about this slowness? What are the reasons of this slowness?
I am giving the below rates (values) which I took from my test (from my comparisons between SAS 10.000 and SATA 7200);
dd if=/dev/zero of=bigfile.txt bs=1024 count=1000000 when this comment was run in SAS disk server, I took this output(10.000 rpm)
(a new server,2 CPU 8 core and 8 gb ram)

I have a server with 48 cores, 8 6-way Opteron CPU's. Ubuntu Server 9.04 only sees 32 processors. Is there a limit on the number of cores/processors that the server will use? Windows 2008 on the same server sees all 48 cores and the so does the BIOS, so this is unique to Ubuntu right now.
I just installed the latest version of Ubuntu 10.04 LTS, and am wondering if support for my dual AMD processors is built into the generic kernel, or do I need to compile a custom kernel? I have an HP tx2-1025dx touchsmart.
I was previously using kernel-huge until a slackware update caused some problems for me, so I switched over to kernel-generic but now I'm wondering if it uses both of my cpus on my dual core processor.
when I start my application it creates a message queue and forks a process. The child process reads multicast packets from the network and writes to message queue. The parent process reads packets from message queue and compares source ip and sequence number (it is part of payload) with last 64K packets received to see if it has received a duplicate packet. I am using message queue as a buffer because I do not want child process to drop any packets while it is comparing it with previously received packets. The message queue is large enough to contain 64K packets. To compare the old packets I am using array of structures as circular buffer. During a spike I may receive 100 - 120 packets per milli second.
When I run my application, the parent process keeps up with the child process, I can see that with "ipcs -q". After about 30 seconds it cannot keep up and the size of message queue keeps increasing until it is full. When I run "top" I can see that one CPU/core is hundred percent busy while other 7 cores are idle. It seems that both processes are running on same core and the child process gets interrupts everytime there is a packet on the net and starves the parent process.I am running RHEL 5. The system has 24GB memory and my application is the only application running on it. It is a HP G6 server.
I just install fedora 15 (64bit) on my Toshiba Satellite L550 laptop.I realise a problem with my fan. It is ON almost allways (90% of the time my laptop is on).My processors are not active and there is no an obvious process that captures my cpu.I had the same problem on fedora 13 and 14 too. I hoped that they solved it in 15.... but... this was not true . When I run it from inside Windows 7 (from a Virtual Machine) it works fine! I was searching to the internet to find a solution (for days) with no luck!Is it a compatibility problem between my CPU and Linux kernel?The problem is very annoying indeed and prevents me for using fedora as my default OS with or w/o A/C.I must say that the same problem exists in ubuntu 10 too
I have 2 CPU 8 GB RAM server running MySQL & HTTP server with apps using LAMP architecture. Since last few days we are having some performance problems.While looking at the problem i came to know both mysql and http are almost taking 100% cpu time of a single processor and the second processor is free. redirecting the mysql load to one cpu and http load to the second one? Is it possible? If so how to do it?
In my Open-Suse server I have a script, where makepasswd output(by default it generates similar passwords: cGyTbqpr, tpJ1LA, 33EXdo) is redirected to mkpasswd(which uses DES by default) in order to generate salted hash of this previously generated password. I would like to test the strength of this system. I have a quad core CPU, and if I start John The Ripper like this(I want to use -incremental:all flag):
john -incremental:all passwd
..only one core is utilized at 100%. Is there a possibility to make all four cores to crack this password? Or is this possible only after reprogramming John The Ripper? Or what is the algorithm for generating passwords with with -incremental:all flag? I mean if John generates passwords randomly in brute-force mode, then it's smart to start four different John processes simultaneously because then one of those four will find the password firs
I am trying to introduce Linux to 7th Grade kids in my society. I have got some very very old PC's with 128MB RAM and some with 256 MB RAM. The processor speed is 1GHZ to 1.5GHZ for most of them. which Linux Distribution will be suitable for it. I want to install them on Hard Disk & rather than booting from the USB drives every time.
Are Intel wireless cards compatible with non-intel-based laptops? In my case I wish to upgrade the current Atheros-based mini pci express wifi card with the Intel 4965agn. It is an Asus 4520 with an AMD Athlon X2 processor and nvidia nForce chipset.
I have recently installed Ubuntu 10.04.1 lts server on my Intel "fakeraid" (software raid) (2x250 sata).To test my RAID 1 I turned off one HD and start the system.The first screen (Intel software screen) show Status = Degraded, but the system starts normally with just one HD.Then I turned off the system and turned on the HD again, so the first screen (Intel software screen) shows Status = Rebuild. If I enter in the software raid panel the folowing message is showed: "Volumes with "Rebuild" status will be rebuilt within the operating system"The system starts normally... but this message status stays permanently even I restart the system again
