How I can disable the driver cache or adjust it better?
I have
/ ext 2
everything else ext4 and my storage drive has xfs.
Anytime I need to do a reset, whatever is in the cache is unreadable afterward. I like to avoid this. The best would be not to have a reset, but sometimes it just happens. Can I do that?
I'm testing OpenSUSE 11.3 on a server and I'd like to disable the write cache on all of my drives. In Ubuntu Server I was able to accomplish this with hdparm by adding the appropriate settings to /etc/hdparm.conf
As far as I can find the only thing that OpenSUSE offers is /etc/sysconfig/ide which allows you to force particular DMA modes. I could just put the hdparm commands in /etc/init.d/boot.local but I'd prefer to do it the right way if there is a right way to do this in OpenSUSE.
The "Check if already posted" brings up no results. I've installed Ubuntu 11.04 with Wubi on my Window7 Home Premium laptop. No problems, except that I can't find "System" to make adjustments, specifically:
(1) Disable touchpad (it is disabled in Windows7).
(2) The display is only using about two-thirds of the screen (11.6" Samsung X120). In the Windows7 setup I do have the resolution set at 125% because the fonts are terribly small otherwise on this quite high resolution display.
During the installation I was not taken thru settings screens for things like language, video, like I have been on the very rare occasions I've installed a Linux OS onto its own partition, presumably because Ubuntu 11.04 is being installed as part of Windows7.
I have Intel X25-V SSD connected to linux machine and its status is shown as "[sdb] Write cache: enabled, read cache: enabled" in dmesg. I knew we can disable write cache using hdparm. Is there any way to disable read cache and is this read cache present on SSD ?

After this when I umount this drive, after 1 minute I got error that this drive cannot be unmounted ( because cache is not stored in drive, umount time limit I think ). How to disable write cache to usb flash drives, change its size or change umount timeout.

We have a xfs partition over a hardware RAID that stores our RAW HD Video. Most of the shoots are 50-300gb each so the linux cache has a hit-rate of 0.001%.
I have tryed the sync option but it still fills up the cache when copinging the files. ( about 30x over per shoot :P )
/etc/fstab:
/dev/sdb1 /video xfs sync,noatime,nodiratime,logbufs=8 0 1
Im running debian lenny if it helps.
It has been haunting me for weeks and I haven't been able to fix it so far: When I installed the wireless driver 43XX series on my laptop using a wired internet, I saw the wireless network for a while and after I rebooted my system, My kernel(31) got corrupted and I got error "kernel Panic (and some sync error)",Thus I started using an older kernel(14),Now When I install wireless driver or mobile broadband driver(wvdial), they get vanished after the reboot and my mobile device modem isn't detected.But they are installed in my system(as shown by synaptic package manager but doesn't seemt to work) I desperately want to use mobile broadband.

I know JohnVV. "Install a supported version of Fedora, like Fedora 11". This is on a box that has all 11 releases of Fedora installed. It's a toy and I like to play around with it.
I was laughing about klackenfus's post with the ancient RH install, and then work has me dig up an old server that has been out of use for some time. It has some proprietary binaries installed that intentionally tries to hide files to prevent copying (and we are no longer paying for support or have install binaries), so a clean install is not preferable.
Basically it has been out of commission for so long, that the apt-get upgrade DL is larger than the /var partition (apt caches to /var/cache/apt/archives).
I can upgrade the bigger packages manually until I get under the threshold, but then I learn nothing new. So I'm curious if I can redirect the cache of apt to a specified folder either on the command line or via a config setting?
I installed squid cache on my ubuntu server 10.10 and it is work fine but i want to know how to make it cache all files like .exe .mp3 .avi ....etc. and the other thing i want to know is how to make my client take the files from the cache in the full speed. since am using mikrotik system to use pppoe for clients and i match it with my ubuntu squid

Where do I adjust the settings for this? I have configured my ATI graphics card succesfully. Direct rendering, desktop animation and everything else is working fine btw.
View 4 Replies View RelatedSuffering from the expected error in detecting my video properly when installed 11.3.Have intel 915G onboard video. Up until 11.1 Opensuse struggled with loading this correctly. in 11.1 & 11.2 all was well. A couple of minor tweaks in sax2 and it worked perfectly. Now hat sax2 has gone I'm not sure how to make these minor tweaks.
My problem is I have been forced to a screen resolution of 1024X768 VGA Following the readme file adding nomodeset at boot fixes the problem but of course forces me back to an old video driver with pretty poor performance. Is there any way I can change the screen resolution and set the correct monitor - any GUI replacement for sax2? Krandrtray will only let me set a max res of 1024x768. I need to set res to 1280x1024

How can one adjust/sync audio and video in gnome-mplayer while watching video
The following is my configuration :-
OS : Opensuse 11.2
Media Player : gnome-mplayer 0.9.9
Computer boots up fine, but drops to commandline as it tries to go to the desktop. Just logging in and issuing "startx" brings up the desktop and all is well.
The Xorg logfile gives no fatals or clues (at least to me), but the "warn" file in /var/log gives the following at the end:
Mar 13 13:25:43 xxxxxxxx kdm[2328]: X server startup timeout, terminating
Mar 13 13:25:43 xxxxxxxx kdm[2328]: X server for display :0 can't be started, session disabled
Yesterday was fine, and never had it before; no harware changes (still same ATI 4770 and ATI 11.2 driver), nor BIOS changes/updates, for ages. First boot today this started. Does it continuously.
how I might slightly increase X's timeout parameter a bit, if this is the problem?

I understand I need to install a driver for it but don't know how. The problem I see with Linux is that it's not easy to install software for new users. I have ran into a few One click Installs and managed to work them out quite easily. Usually the documentation you find online to install programs assumes the end user knows how to install.I need to know how to install the touch-pad driver from start to finish and all steps in between.

View 4 Replies View RelatedMy laptop screen suddenly fails to show anything else than a black screen. Hence I would like to connect it to another external screen in order to debug and/or data backup for a new computer.When I connect it to an external screen and boot the system (Fedora 13) I see the different services getting started succesfully on the screen. In the end of the boot procedure usually my proprietary Nvidia driver loads (recognized by the big Nvidia logo) - but this fails to show up on the external display. So from the point where the Nvidia driver usually loads I have no working display.
I think I know why. It's because I installed a proprietary Nvidia driver and saved the configuration in Xorg.conf - and the saved configuration does not include this particular external display. So now the driver insist on starting on the non-functional laptop display.
Here comes the question: can I somehow stall the boot process (while it is shown on the external display) and disable the driver (and delete the Xorg.conf file)?
