[01:05] have Dell Laptop A860 Core2 Duo wishing to install Ubuntu 10.10 with 4 Gigs RAM [01:05] is it better to go for 32 Bit or 64 Bit [01:07] In my experience if you have a computer that is 64bit capable there is not reason not to go with 64bit but there will be others who disagree. [01:07] ok [01:08] So video card Memory is shared in RAM [01:09] That has nothing to do with 32/64 bit it's got to do with what specific hardware you have [01:10] ok [01:12] so is there a way to know how much RAM a Video Card uses ? [01:12] is it cat /var/log/Xorg.0.log | grep RAM [01:12] Not sure, I've only ever had video cards with their own ram, not system shared [01:13] so i did ran that command [01:13] is it cat /var/log/Xorg.0.log | grep -i RAM [01:14] is it returned 256MB [01:14] Sorry mate, I wouldn't know where to start. It's possible though as that sounds about normal. The laptop specifications should list how much it uses though [01:15] head_victim: sure [01:15] head_victim: Thanks [01:15] so ideally I should go for 64 Bit [01:16] I would use it but for some reason http://www.ubuntu.com/desktop/get-ubuntu/download always suggests the 32bit as recommended. I personally haven't had an issue with 64bit in a couple of years. [01:17] https://help.ubuntu.com/community/32bit_and_64bit [01:17] I guess the decision is split depending on what website you're looking at. [01:22] head_victim: At the moment I am running 32 Bit 10.10 [01:23] is it better to use pae kernel or better to use 64 Bit OS ? [01:24] what are you running? do you have more than 4gb of ram and do you have a program that will need more than 4gb of memory? [01:24] nope [01:25] I have just 4 GB RAM [01:25] personally i'd run a 64 bit os, but flash is not quite as stable [01:25] but the 32 Bit OS reports 3.4 GB and out of 3.4 GB 256mb is shared by Video Card [01:26] flash ? [01:27] yes, that is why you need a pae kernel (this is a hack to allow a 32 bit os to address more than 3 gb of memory) or a native 64 bit kernel [01:27] ok [01:27] dns53: i didnot understand about flash ? [01:27] adobe flash has a 64 bit port, it works but it is not the best port [01:27] oh ok [01:28] it's fine for me, but results may vary [01:29] dns53: so i would reinstall 10.10 with 64 Bit OS [01:29] head_victim: Thanks [01:29] dns53: Thanks [01:29] apologies for bugging [01:30] nothing wrong with asking [01:33] No worries at all [01:44] Also I have found something interesting also [01:45] so HT means Hyperthreading [01:45] http://www.brandonhutchinson.com/Understanding_proc_cpuinfo.html [01:45] so HT is enabled in the BIOS ? [01:46] and I have HT as flag in cpuinfo [01:46] so to use HT i need to use SMP kernel ? [01:46] please help me understand [01:48] so hyperthreading can be disabled in the bios as it could potentially cause problems [01:49] ok [01:50] there is no smtp kernel any more, you do not need a different kernel to use smtp anymore, you did need one 1998-2002 ish [01:50] oh ok [01:50] dns53: ever seen an issue with HT though? [01:51] dns53: you said potential problems [01:51] head_victim never, but bios manufacturers put flags like that in case there are problems [01:51] not sure i understand that [01:51] dns53: ah ok, just curious because again I'd heard it was possible but another of those things I'd never seen in real life. [01:51] so it is not a problem but it was new so they have the option to dissable things incase [01:52] Yep, sounds fair. [01:52] head_victim i've had occasional problems with the virtualisation extensions so it can be useful to have [01:53] dns53: ah ok, I guess it would make sense to be able to switch "features" on and off, especially from a "stable" point of view. [01:54] kaushal back to your question, hyper threading is more like 1 1/2 cpu's, so you can do a little more than you would if you just had the single core === kaushal2 is now known as kaushal [01:55] dns53: sorry i got disconnected [01:56] ok [01:56] a computer does processing a small chunk at a time, so you would read a file for a fraction of a second, draw something on screen for a fraction, read something off a network etc [01:56] so hyper threading allows the cpu to do one thing and part of another thing in the time slice [01:57] ok [01:58] so if i enable HT in my BIOS [01:58] if I am having Core 2 Duo [01:58] so it would lead to issues ? [01:58] as far as yes [01:58] i have not heard of any problems, you get more performance [01:59] dns53: but you said potential problems [02:00] there are none but hardware manufacturers put things in because it is almost impossible to fix later [02:01] ok [02:01] Also as per http://www.brandonhutchinson.com/Understanding_proc_cpuinfo.html [02:01] it specifies about Intel [02:01] How do i understand if its AMD [02:03] it will have it will say: vendor_id : AuthenticAMD [02:03] my server's cpu info: http://pastebin.ubuntu.com/542134/ [02:04] yes [02:05] but how to make out ifs single core or dual core [02:06] you look and see how many cores it describes, amd does not have hyper threading [02:07] it says 2 cores [02:07] so its a single physical processor ? [02:07] it probably has 1 [02:08] 1 chip itself, 2 cores [02:08] ok === yama` is now known as yama [05:31] Is it just me or has FF been a bit crashy of late? [05:50] My bad, it's flash that's buggy, not FF. [08:22] hi [08:22] can someone please guide me to install Flash on firefox 64 Bit [08:22] I am on 10.10 64 Bit OS === yama` is now known as yama
