first, sorry for my bad english, I am german I have a problem enabling IOMMU on my MSI 970A-G45 mainboard. I need the IOMMU support for PCI passthrough in KVM ( I need my DVB pci cards in the virtual machine).
I have installed Ubuntu server 11.04 and enabled IOMMU in bios. The first strange thing is, that when iommu is enabled in the bios i cant access network or USB devices in ubuntu. Only when its disabled in bios.
Well, i tried the tutorial from here: http://www.linux-kvm.org/page/How_to...th_VT-d_in_KVM and compiled a new kernel with "Support for DMA Remapping Devices", "Enable DMA Remapping Devices" and "PCI Stub driver" enabled and installed it (based on description in wiki)
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.
I am using RHEL 5. I have enabled rpmfusion, epel and rpmforge yum repositories and installed Audacious and dependecies. But I could not find any mp3 playback plugins. Installed Audacious plays ogg format but doesnt play mp3. How can i make Audacious play mp3 format ?
All of those items listed above are potential points of failure in this situation, and any help narrowing them down would be fantastic. I am simply trying to enable webcame support directly through Facebooks website.
Forum searches and the usual googling turn up few posts related to this specific equation. Two of the major suggestions include:
1) Installing the Sun (I refuse to say oracle sob)-provided Java implementation instead of the OpenJDK normally installed in Ubuntu. And yes, after installing it, I did update all my default supports to use the sun commands over the openjdk.
2) Somehow enabling Facebook as a permitted site to access my webcam using Flash settings.
I have not been able to explore option 2 because I cannot find a way to adjust the Flash settings in chromium 7.
I have tried many ways to enable vdpau support in my machine but for no avail. A member here helped me very much but I couldn't manage to succeed. My system has Ubuntu 9.10 64-bit, Nvidia 8500GT 512mb, Intel Core 2 duo. I have installed Nvidia driver version 195 currently available from their site. I tried compiling mplayer with vdpau support from various tutorials thread here around in Ubuntu forums.
Is there anyone in this forum with Ubuntu 9.10 64 bit with the same other system requirements as mine who have successfully managed to make the VDPAU work?
I've upgrade my hardware configuration up to 4GB of RAM. Today I've found some problems with my Ubuntu 10.10, like music stops playing or file system that became read-only. I've found this errors messages running dmesg:Code:PCI-DMA: Out of IOMMU space for xxx bytesI've tried to add "iommu=memaper=3" and "iommu=noaperture" to boot options as found with google, but problem still remains.
Configure desktop (Desktop - System Settings) --> Desktop Message indicates: Compositing is not supported on your system. Required X extensions (XComposite and XDamage) are not available.
I can't find XComposite or XDamage as a package to install with Software Management. code...

trying to understand the two underlined sentences below I got to ask Step by step. I created a new group called usb. I inserted a usb printer and scanner. I tried to find the file usbfs and there is where get stuck already. I only can find a folder with that name. The sentence (3 -) makes almost no sense to me.
a) modify file /etc/fstab clear open terminal, go to etc, su gedit fstab
b) inserting a line yes I understand that!
c) the right path and the number corresponding the "usb" group :
I have ubuntu jaunty 9.04 installed in my system(thats my only OS.. no dual boot). When I tried to install hplip to enable hp printer driver, I understood that 9.04 is obsolete and no more support for it. I want to upgrade now. Update manager shows '10.04' for uogradation but it seems I cannot jump from 9.04 to 10.04 without getting into 9.10.
I'm struggling with my computer to get it to run a Windows 7 x64 machine as domU with VGA passthrough using Xen and Fedora 14 as dom0.
The problem is that when I enable IOMMU in BIOS, it simply freezes during boot. If booting with the dom0 pvops kernel via Xen it stops at the "IOMMU enabled" message. If I boot the regular unpatched kernel without the Xen; all I see is naught but a blinking cursor at the upper left corner.
I tried booting from the Fedora 14 liveCD and the lubuntu 10.04 liveCD and they booth freeze in a simlar fashion afer I get past their bootloaders.
The Windows 7 partition boots just fine and I can do all sorts of stuff in it (such as conducting computationally intensive tasks) without problems.
This affects any version of Linux I have managed to put my hands on, 32 bit as well as 64 bit, except XenServer 5.6. This does not affect Windows 7 x64, GRUB bootloaders and FreeDOS/MSDOS based boot CDs. Also, Linux boots fine with the BIOS IOMMU feature disabled.What happens is that the 64-bit Linux install, bootCD, installCD, liveCD or USB hangs almost immediately after GRUB with naught but a blinking cursor at the upper left corner. Some liveCDs manage to show some kind of boot splash before it hangs. USB peripherals such as the mouse and the USB stick gets severed at the moment of the hang. The num-lock led is on but the keyboard is irresponsive to *-lock toggles.
In the 32-bit version it takes a little longer before the hang and the USB peripherals stay on at the event of the hang, but the keyboard is irrespnsive in the same manner. It also spits out error messages.
I recently installed Deluge 1.2.0 from the following PPA:[URL]I using this on two different Linux computers. One is running Linux Mint 8 and the other is running Ubuntu Netbook Remix 9.10. The first time on either computer when I enable WebUI in the Deluge GUI it works fine. However if I ever disable it in plugins section I am subsequently unable to re-enable it (doesn't appear in the side panel again). Rebooting or reinstalling Deluge seems to have no effect.Is this a bug or am I doing something wrong?
In understanding with Fedora logs are trying to tell me and if I need to adjust some settings on my system to address these issues.
The system motherboard (Gigabyte GA-MA785GT-UD3H) has onboard graphics. I understand that some of the system RAM is taken up by the graphics subsystem.
Very occasionally, I am seeing Nautilus and some other apps crash with SIGSEGV errors. Also, on the couple of occasions, parts of the display started going black - minimising and maximising the window redrew the area as before. This appears to be to do with memory access issues. I have already tested my RAM, applied the latest BIOS update on the mobo. I'm trying to understand if this is some sort of memory access violation that is resulting from the Linux kernel going off and accessing the wrong parts of the RAM and if there is a way to tell it that the graphics and system areas of the RAM are separate, through BIOS settings or kernel parameters and such?
Some questions:
1. Is my system using AGP? I don't think so. I understand AGP is on its way out. So what does the below log output mean wrt AGP?
2. Which part of the log is actually describing the memory assignment for the graphics memory?
3. Would it be of any use trying iommu=noaperture here? I am trying this out, but I don't understand if it is helping in anyway.
Have done a Google search and read on AGP, iommu, shared memory for graphics, but their interaction with each other at the hardware level and how Fedora is handling this is not sinking into my dull brain.
I have put up the system configuration, BIOS settings, logs etc for your perusal here [url]. Parts that caught my attention are highlighted.
I had the elrepo kmod-r8168 driver running smooth for a while on my development box. Yesterday, I did a clean install on it and when I tried to install the latest kmod-r8168 rpm, it failed to enable the networking support:
# yum --enablerepo=elrepo install kmod-r8168
The install performed all proper steps to disable the 8169 driver, I double checked to be sure.This is not a connectivity issue. If I remove the kmod-r8168 rpm, reboot the server and run the ifconfig eth0 up to activate the interface, everything works as expected. I use the latest kernel (2.6.18-194.26.1.el5 x86_64).
First, I performed a clean install, activated the eth0 and did a yum update, then installed the kmod-r8168 with yum. Then, I reinstalled the OS again, activated the eth0 and installed the kmod-r8168 on a 5.5 CD based kernel, same fail results. The only hiccup is: every time I start the box, I have to activate the eth0 interface (with default CentOS 8169 driver):
# ifconfig eth0 192.168.1.3 # ping -c 3 192.168.1.1 (no packets lost) # ifconfig eth0 up
I see "Virtual Directory Support" is disabled in phpinfo.php, how can I enable it ? I didnt find any option in php.ini related to Virtual Directory Support.
I just bought a dual USB2/USB3 external disk for backup purposes on my Ubuntu server box, running 8.0.4 LTS. For various reasons I can't upgrade to the newest LTS yet and I was wondering if there were any plans for USB3 support on Ubuntu Server 8.0.4?
I bought a new ve server from Media Temple, but can not figure out how to enable/install/whatever FTP access to it? I just want to set it up so I can use transmit on my server. Do I hace to install FTP? What is the best way to do this?
I am installing a new large 4 Tb RAID (hardware) under 9.10. Does GPT support come by default in the new 9.10 kernel? How can I check? I gather I need to use PARTED to make a GPT partition table on the raid. Anyone know details of how to do this? [URL]...
Ive had my server up and running for a few weeks now, everything has been good. My one small hitch is that while in the console I need to be able to see Chinese Simplified characters. I dont really need to type them, but I do need to be able to read them. How do I go about adding support for simplified chinese?
I'm testing a support ticketing system (osTicket), and am trying to set up the server so it can send and receive messages using an external email account so it will, you know, work.When you try to add an email account, it spits out the error "IMAP doesn't exist. PHP must be compiled with IMAP enabled." in the web interface.So apparently IMAP isn't enabled in PHP. And apparently I have to recompile PHP to add that particular function. Um... how i do that? i not so good with computer
I'm not having any luck today getting maildrop working. Ubuntu (Hardy) and everything is from aptitude.If I use 2.0.3 (the version aptitude serves up) I get this:
This is after I made maildrop setuid root. It seems that the version aptitude serves us was compiled without the --enable-trusted-users flag at compile time. There appears to be no way around this other than to recompile, according to Sam V, the author of the program. So I'm off to compile my own.
/usr/local/bin/maildrop -v maildrop 2.4.2 Copyright 1998-2005 Double Precision, Inc. Maildir quota extension are now always enabled. This program is distributed under the terms of the GNU General Public License. See COPYING for additional information.
[code]....
It never talks to mysql and obviously isn't authenticating. The aptitude version does talk to mysql, but can proceed no further because it hits that "trusted user" issue.
Are the authlib & mysql libraries somewhere else? There areHow can I solve this? Have any of you successfully compiled maildrop to work with courier-authlib and mysql? This is driving me nuts. I'm using courier-imap with virtual users in mysql. This setup has worked just fine for a long time, but I now need to add server side filtering. It seems like I'm almost there....
trying to enable sound in Ubuntu Server! I have 10.04 Server x64 on an atom (Dell A100) that I need to enable sound for a legacy device that is running in a Windows VM through a com port (all working fine bar sound)I have followed these instructions for sound issues guide, with no joy![URL]I actually have 2 identical machines, with Ubuntu Desktop on the 2nd the sound works fine, but I'd rather not install gnome etc to fix the sound! On the server:
Code:
user@server:~$ aplay -l aplay: device_list:223 no soundcards found...
On the 2nd machine:
Code:
ubuntu@ubuntu:~$ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: Intel [HDA Intel], device 0: ALC662 rev1 Analog [ALC662 rev1 Analog]
[code]....
I presume the 'Kernel modules:snd-hda-intel' means the Intel driver is actually installed but I tried rebuilding the alsa driver from source anyway (selected hda-intel)it compiled successfully. But the server still says no soundcards found with the command: aplay -l I also tried adding snd-hda-intel to the bottom of /etc/modules but still no joy!
