Ubuntu :: Any Way To Trim 9.10 Down (Lightweight)?
Mar 30, 2010
I was running it portable on a 4gb usb drive via virtual box which worked great unless I used a computer that had virtualbox on it. The portable version would remove files that the original version needed. I decided to try Qemu. The problem is that the portable version only allows 1gb of space to install regardless the size of a usb drive. so the question is: Is there was a way to trim ubuntu 9.10 down to less than 1gb of disk space? If not is there another portable emulator that could be used instead? the only uses for this are for the use of evolution and opera in a linux environment.

I have an OCZ Vertex SSD...the 30GB variety. recently I upgraded my kernel to 2.6.33. I have read that that is all that is needed in order for trim to just start working. Is there a way that I can verify that TRIM is working?I'm debating getting the Vertex2 100GB model because I love my SSD now, but would love to have a little more storage space. I just don't want to buy it without TRIM working.

For anyone who is not familiar with it, I am talking about the trim functionality in the 2.6.33 kernel for solid state drives.

I followed this tutorial [URL] to enable my TRIM support and now my fstab looks like this:
Quote:
# /etc/fstab: static file system information.
#
# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name
# devices that works even if disks are added and removed. See fstab(5).
[Code].....
but when I follow the second half of the tutorial http://lightrush.ndoytchev.com/rando...bledandworking to check and make sure it's working I don't get all zeros like I'm supposed. I tried waiting a while like I saw in another tutorial as well and check it again.. Still random numbers and no zeros.

My issue is that I have a small VPS (512MB, 1024 burstable RAM) and I am planning on using it as an application server for say a voice server and maybe a small game server.
Coming from a Windows background, the only way I know to do this is to have a GUI + Remote Desktop and download + install the servers and run them as one normally would on a desktop PC.
But obviously this would eat up a considerable amount of my RAM.
Is there a way to download and run something like Teamspeak 3 just through the kernal alone?
If possible, is it worth the hassle (especially if I am running multiple server applications)? Or am I better off using a desktop environment + Remote Desktop?

The situation with TRIM in Ubuntu has me utterly confused. I don't know whether I need to manually run it or not. Sources I've found are disparate and unclear. I have Ubuntu 10.04 with latest updates (including kernel 2.6.32-26). I have an Intel X-25M drive with latest firmware, and it is formatted as ext4. So, does TRIM support run automatically? If not, how do I check if I need to run it, and then how do I run it if necessary?

In windows the only controllers that really work with TRIM is the onboard Intel ones, Jmicron, Marvell, Nvidia and AMD's don't pass the command to the drives if you use their own drivers. (And from what Ive read, the Micron sata6 controllers don't work with TRIM even using the default Microsoft drivers). In Linux do more then just Intel drives work with TRIM? I have a Nvidia 790i Ultra motherboard, the SATA controller is an Nvidia one which has 2 settings, ATA and Raid (if the drives aren't added to an array it runs them in AHCI) and has an additional Jmicron sata port.
If I enabled TRIM in the OS, would it work on either of those controllers? Also if anyone knows this, in Windows if you set an Intel controller to raid, you wont get TRIM on SSD's that are on the controller (but not in an array) with the default Microsoft driver like you would if it was set to AHCI, you only get it with the Intel RST drivers. Would a SSD on an Intel controller set to raid but not in an array get the TRIM command passed to it in Ubuntu?

We're planning to install CentOS on a new server that will be based on two Solid-State Disks in a RAID1 configuration. The RAID management will be handled by a hardware Adaptec controller. I've learnt that the TRIM function for SSD drives is supported starting from kernel 2.6.28.

With gnome-do, you can do things as quickly as possible (but no quicker). In a low-spec application, the 'do uses up ~16mb of ram even in idle mode, if I recall correctly. Are there any lighter alternatives to gnome-do? It's so useful - but I feel like its functionality could be even snappier.

My Hard Drive in my PC went poo poo, so until I get a new one, I am going to be running off of a live cd for a while. What is a good small distro that is lightweight enough to be used on a Pentium 4 and 512mb of ram?

I tried to trim a video in FFmpeg using this command:
Code:
ffmpeg -ss 00:20:48.500 -t 00:01:00 -i INPUT.mp4 -acodec copy -vcodec copy OUTPUT.mp4
But FFmpeg is not accurate and it started the video from a nearby point instead (from 00:24:46~). I tried to add 2 seconds to my starting point and it took another frame (not what I wanted).
The video source is H264 video with AAC audio.

Ok, Im likely to buy SSD 128gb drive and install Fedora 14 on it...but I have a question. If I go with ext4 will I get TRIM to work out of the box? Whats the status of kernel support on trim?

First system specs. Gateway Solo Pro 9300, 433Mhz, 288megs. OS Slackware 13.1 32-bit and KDE.
As I get more comfortable with Linux I find that I am doing more waiting for the computer to catch up.
Would it be better to trim down KDE or change to a lighter GUI? If I change to a lighter GUI will I have to reinstall things I have installed under KDE?

Does CentOS 5 support the ATA TRIM command for use with SSDs? Is the support automatic by default, or would I need to do something specific in order to enable the TRIM feature be used?

I am trying to set up an atom D525 low power PC 64-bit with a 40 GB solid state disk drive. Is it possible to specify ext4 during the install for proper SSD suupport? I read somewhere that after install I can place a -discard line in fstab to enable trim.
Edit: should I have asked this in the x86_64 forum, as I was planning on installing 64 bit?

I recently tried to install Ubuntu on an old disused laptop I inherited. I bought a new hard disk just for the purpose. Unfortunately it crashes when trying to install Ubuntu/Xubuntu/Mint. Long story short, not enough RAM and an old processor are the cause. I was wondering if there are any very lightweight OS out there for old computers. I realize it depends on what I want to use the laptop for. But I dont know what I want to use it for until it is usable. SO I'm just looking for anything. I found this linux distro : [URL]..

I just bought a Samsung 850 Pro 250GB SSD drive and have since then found out that Linux has/had a faulty implementation of queued trim (which is a synonym for NCQ I think). I'm using kernel 4.1.0 (the default selected by the Debian 8.1 installer) and I've read that Samsung drives are blacklisted for queued trim by the recent kernels. However, the output of dmesg contains the following lines, with and without TRIM enabled for the drive (i.e. with or without the "discard" option in fstab for the drive):
Code: Select all[ 1.012287] ata6.00: 1953525168 sectors, multi 16: LBA48 NCQ (depth 31/32), AA
[ 1.013438] ata5.00: failed to get NCQ Send/Recv Log Emask 0x1
[ 1.013440] ata5.00: 488397168 sectors, multi 1: LBA48 NCQ (depth 31/32), AA
[ 1.015037] ata5.00: failed to get NCQ Send/Recv Log Emask 0x1
Since the depth is not 1 but rather 31, it looks like NCQ is enabled. I've disabled TRIM on the drive for now, and whether it's safe to enable TRIM or not.

Does Suse have any software based TRIM support available or that is in the works?I know there is to a degree new firmware becoming available that supports TRIM (although some are pretty rudimentary) but windows 7 does a fairly good job software side and upgrading the firmware occasionally involves the unbridled joy that is wiping the drive and starting again.

There are not SSDs with TRIM support available in my region that fit into my laptop (1.8", IDE, ZIF). I'm running Ubuntu 10.10.
Most articles (or questions on superuser) I've come across concering TRIM (or the lack thereof) date back to 2009, when not many SSDs with TRIM support were available and OS support was still very fresh.
I'm interested in the current situation, but I couldn't find too much information about it.
What are currently the "best practices" for using an SSD without TRIM under Linux?
I've read about the wiper script included with hdparm. Do I understand correctly that I could use this to free unused blocks, e.g. by running it once a month?
Some sources state that HFS+ (the default-filesystem of Mac OS X) doesn't suffer as badly from lack of TRIM as other filesystems. How about linux filesystems? Are there filesystems that are better suited for SSDs without TRIM than others?

After installing UNR, I found the unity interface to be lacking advanced features, support on forums and tweaks. So I installed the ubuntu desktop, but I kept maximus (and tweaked the list of apps which shouldn't be maximized, so I am pretty happy with maximus). Since netbooks aren't as fast, I wanted to get a more lightweight desktop environment. I started with replacing Metacity with Openbox (since it seems to be quite popular). I noticed that after logging in my memory usage was 186 MB and 189 MB after running ubuntu tweak, for both window managers. If Openbox would be as lightweight as it claims to be I find it rather strange that I don't notice any difference in memory usage. (about my "test": I changed the default window manager using ubuntu tweak, logged out and logged back in to start a new session, opened system monitor to measure memory usage)

I would like to know if there is a window manager that has no decorations (window borders etc) and shows all opened windows in a tab bar. I am using gDevilspie at the moment to undecorate the gnome (metacity) window borders on all windows, but i wondered that my computer could be so much faster, because i dont really need any of that eye candy that gnome provides. I just sign in to ubuntu, and open firefox.

I am trying to install debian on a slow netbook, and I can only install to a bootable SD card. The SD card is 200x, so it should be fairly fast. I was just wondering what filesystem would be the fastest, and use the least amount of cpu. I think it should be a non-journaling one, since this is flash media. I was thinking ext2 originally, but I heard ext4 has a non-journaling option, and is faster. However does ext4 take up more cpu usage?

I'm moving over to Linux when the new SSD arrives. SSD gives increased performance, so I thought that I could encrypt everything.
But then I came to think about TRIM, and garbage collection on the drive. Will a LUKS encrypted drive affect the garbage collection system? (TRIM).
