With the new Intel G2 SSDs coming out, I'm thinking about upgrading my hard drive. However, there seems to be an extra level of software support needed for SSD drives. From what I have read there can be performance degradation over time and other issues. Does anyone know how well SSD drives are supported in Linux and also if there is support for the TRIM command or if it is planned?
View 10 RepliesThere 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?
I was looking into getting some solid state drives for the 1st time. I have always used Seagate traditional SATA drives for my home systems but I think I would like to try something new and that has much better performance. Do you guys know if I will see any performance gains and or issues using SSD on Linux? I run Arch and Debian Linux in general...

View 6 Replies View RelatedHad a laptop with a Hardy install - my two year old knocked it on the floor and after that it no longer recognized the drive, and I could hear the hard drive read head hit the platter when it tried to read it.
I bought a new Kingston 128GB solid state drive to replace my old 40GB drive - figure it will be more robust.
I tried installing Lucid, and it stopped after partitioning the drive and was unable to format it. I attempted to use my old Hardy install disks, and had the same issue. I spent time with Kingston tech support, they had me try a few things, then RMA'd me a new drive. New drive still had the same error.
I figured something else must've broke and let it be for a while. Today, just for the heck of it, I attempted to install XP on it. Flawless. So, it's not a hardware issue.
Any known issues with the Ubuntu installer and Laptop SATA-2 Solid State Drives? (I'll put more details in a later post if needed, don't have them at this very moment)
I'd like to build a compact x86 host running off a CompactFlash or some equivalent solid-state memory instead of from a SATA disk, to reduce the risk of failure once they're deployed at customers' premises. Those are SOHO users, so performance is not an issue, but stability is (The less I have to drive to replace faulty hardware and restore data, the better.)
Do you know if the usual suspects (Ubuntu, CentOS, Gentoo, etc.) can easily be made to run from solid-state memory, and if yes, is there some good documentation to customize them thusly?
I assume it's just a matter of tweaking /etc/fstab, but it could be more involved.
I'm having a particular problem trying to partition a solid state drive on a Dell Mini 9; I'd like to install Ubuntu Netbook on the computer. The machine came with MS Windows XP on it. When I try to use the automated installer, it fails and quits at the partitioning stage. I have tried both fdisk and parted but both of these also fail and quit with errors when they try to write to the disk. I've also tried using Fedora and Knoppix to install and they both fail as well. I did check in the BIOS that the drive, supervisor and user passwords are clear.
Some technical bits that fdisk chucks out;
[ 1913.488878] ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0

[ 1913.511226] ata1.00: status: { DRDY ERR }
[ 1913.517018] ata1.00: error: { ABRT }
can get access to partition the drive or diagnostics to tell what is the problem with the drive?
60 gigabyte SSDs are down around US$100.
It seems like the optimal use would be as a cache for the regular hard drives in my computer. Eliminating the need for a fast hard drive, so I can just use a slow 2TB (~US$100) drive with a SSD cache.
Is there a good way to do this yet?
It seems like it would be nice to be able to exclude some files from caching, for things like bittorrent.

I am wondering if Ubuntu support ATA TRIM for SSD out of the box?
View 1 Replies View RelatedI 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).

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.
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.
View 1 Replies View RelatedThe 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?

View 9 Replies View RelatedMy experience with external monitors in Linux is harrying at best. It's getting better, but it still ain't perfect. My current experience (I have an nVidia card, with nVidia drivers, on a Vostro laptop):
Turn on computer (booting Karmic).
Connect external monitor
Click on System->Preferences->Display
Redirect to nVidia's tool
Perform at least 8 more clicks to enable secondary monitor.
Realize resolution isn't optimal and set it with another few clicks.
Click Apply
Accept changes
Quit, then really quit, the app.
I always have to set the resolution, it doesn't detect it automatically. The main screen is *always* on the external monitor no matter my settings. I'm screwed if I unplug the monitor but forget to go through steps 1-8, this time disabling the external monitor. I have to replug it in, then turn it off, then I can unplug it. If I unplug the external monitor and plug in another one (going through steps 1-8 twice more) with different resolution capabilities (e.g. a projector), the settings get all messed up again.
Why can't adding an external monitor be automatic? It nearly is on OS X for instance. I plug it in, and it automatically detects the monitor and makes it a secondary monitor, or mirrors them, or turns it on and turns off the laptop screen. All the while being consistent about it. When I unplug the monitor, it knows instantly that I've done that, and reconfigures the laptop screen once again.
I imagine the answer is because no one has stepped up to do it yet, or it's in progress. So my question: what *is* the state of external monitor codes in Linux, and are there any plans to implement them in Lucid? Further, what would be a project, with *user friendly* context, to which I could tune in?
Or, am I not aware of the "right way" to do it?
I define user friendly as roughly the level of kernelnewbies.org . That is, kn.org is my gauge of what I can understand.
I was thinking of trying out the UEFI support that HP has in my laptop BIOS in the next few days. My reasons is that I get a custom boot logo... and (hopefully) a better boot-speed. What is the current state of affairs with the openSuSE UEFI/EFI install support on a empty hdd for x86_64 does anyone know? (badly worded I apologize) This may seem naive but I have struggled to answer this with most posts being about Mac's for obvious reasons.
Specifically, Do I have to have any custom knowledge on formatting the HDD with a GPT partitions or does the installer do this for you? Secondly, How well does the UEFI bootloader tie in with the config tools in YaST2? (I would like to have UEFI but if it turns into some headache in setting up the boot area by hand each time the kernel updates I will forget it.) I can safely say this will be a machine with only openSuSE installed as an OS, no need for any others or any dual-boot problems. This isn't overly urgent and I will dedicate (at least) a whole weekend to tweaking once I buy a new disk and install openSuSE on it. If nobody knows then I will dive in head first and report how I find it and any problems (and severity).
Is there a command I can implement into a script that I am working on to change the maximization state of a window (maximize/restore)? I know there is a keyboard shortcut (Alt + F10), and I'm not interested in doing that.

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 would like to create the shell which would support the LS command in C++. And any way to change the command prompt.

I'm a bit perplexed on this issue. I searched through Google looking for similar issues and can't seem to find one that quite fits and I was wondering if someone else has heard of this happening.
I recently installed Ubuntu 10.10 (32 bit) on a friend's Dell Inspiron 1501 to replace the entirely screwed up Windows Vista that was on it. The install process went without flaw or issue. Everything worked perfectly out of the box. My issue comes when I try to copy files from my terabyte external onto the computer (the files she had backed up from her vista install). Files larger than about 300MB cause the computer to freeze up solid. The only thing that works is the power button to force shutdown. There's no mouse... nothing. This made me think there was a hardware issue but...
The external drive has no issues on any computer other than this one so I'm inclined to think the Dell is causing the issues. I ran Ubuntu's drive test and it reported no errors, and MemTest 86 comes up with no errors.
So, I'm looking for some educated guesses. If Ubuntu can handle installs and lengthy updates with no problem, but then connecting an external USB HDD and copying over files causes it to freeze up tighter than I've ever seen Ubuntu freeze before... could a faulty USB port cause this? Motherboard? Ubuntu itself? I'm installing Ubuntu from CD.
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.
