  • Create a package for official Realtek ALC665 drivers (Dell XPS 15 L502X)

    - by Nic
    is it possible for someone to create an ALSA driver package from the official Realtek "LinuxPkg_5.17Beta.tar.bz2" drivers (found via Google)? These drivers provide excellent support for the ALC665 chipset, found eg. in the Dell XPS 15 notebook series (L502x). All the features like output selection (HDMI, headphones) that were not working before are supported. I am asking for a package because the driver is unusable as-is: it comes with an outdated version of ALSA that does not compile on a 3.5 kernel. Apart from that, it also removes all the default snd-* drivers that come with the kernel package. Any help in bringing better support for this device to the official Ubuntu packages is much appreciated. N.

  • HighPoint RocketRAID 62x Controller

    - by TeXnewbie
    I have the subject card recently installed in Ubuntu 12.04.1 LTS (GNU/Linux 3.2.0-31-generic x86_64). See partial lspci -vv listing below (complete listing played havoc with pre tags): 03:00.0 RAID bus controller: HighPoint Technologies, Inc. Device 0622 (rev 01) Subsystem: HighPoint Technologies, Inc. Device 0001 Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Latency: 0, Cache Line Size: 32 bytes Interrupt: pin A routed to IRQ 11 Region 0: I/O ports at 9c00 [size=8] Region 1: I/O ports at 9800 [size=4] Region 2: I/O ports at 9400 [size=8] Region 3: I/O ports at 9000 [size=4] Region 4: I/O ports at 8c00 [size=16] Region 5: Memory at fdbff000 (32-bit, non-prefetchable) [size=2K] Expansion ROM at fdbe0000 [disabled] [size=64K] Capabilities: I followed instructions I found at https://help.ubuntu.com/community/RocketRaid to compile the drivers for it, and although performing the process described there seemed to work fine with no noticeable errors, when I rebooted after performing that procedure I could not boot. During dkms steps, I noticed messages indicating that (If next boot fails, revert to initrd.img-3.2.0-31-generic.old-dkms image) update-initramfs................ so I booted using a Ubuntu 12.10 LiveDVD and reverted to the old-dkms initrd.img as suggested above, but this failed to repair the boot problem. Ultimately, I used https://help.ubuntu.com/community/Boot-Repair in Ubuntu-Secure-Remix to fix the boot problem and was able to boot normally again, but now with the newly generated initrd.img in place again (which now boots normally), when I modprobe the rr62x kernel module, I immediately get a hard crash with messages to console about a kernel paging request that seems to have caused the problem. I've tried on multiple occasions now to use the newly built kernel module so as to allow me to use an eSATA port multiplier plugged into the card, but to no avail. Any suggestions on fixes or workarounds (I've read that some of the HighPoint cards (2720SGL) seem to work as a host bus adapter and thus may not need a custom driver, but that seems not to be the case for mine) would be most appreciated. My goal is to use the card as described here and with software RAID mdadm utilities. If necessary, I can hand-copy the console messages after the hard crash into a follow-up message, but I obviously can't do a cut/paste. I'll gladly provide any other details that are needed, but not sure what those would be at this point, so I'll refrain from adding other details for now. Thanks in advance for any help.

  • check support of Universal TUN/TAP Device on ubuntu 12.04

    - by nmaybar
    I am trying to setup Appgate Ip tunneling driver on my ubuntu 12.04 by following appgate instructions listed below: Installation, Linux Make sure the kernel has support for the Universal TUN/TAP device driver, and then log in as root and create a new directory somewhere, and copy the files ag_iptd add_route add_gw_route add_hosts_entry ag_iptd clean_hosts_file del_route del_gw_route del_hosts_entry interface_down interface_up remove_dns_server set_dns_server fix_localhost into that directory. Then start the IPTD daemon by doing modprobe tun <directory-somewhere>/ag_iptd There is also an init script 'ag_iptd.init' that can be installed to automatically start the IPTD daemon every time the OS is loaded.Please check the documentation of your Linux distribution on howto do this. so is there any way to checkif my ubuntu 12.04 kernel has support for the Universal TUN/TAP device driver? and how to do so? Thanks,

  • Trouble after Ubuntu 12.10 upgrade

    - by highsciguy
    Over night I tried to upgrade to (k)ubuntu 12.10. Unfortunately kdm (neither lightdm) doesn't show up after boot. I found several posts describing errors due to the migration from kdm to lightdm. Some sugest reinstallation of kdm. Therefore I logged into a shell and tried to install it using apt-get. However it turned out that network is not available. ifconfig showes that only the loopback device lo is available. What can I do to get lan or wlan network working on the commandline? I relized that grub still runs the old tuxonice kernel which I installed from ppa. Is it possible that the installation didn't finish and left me in an inkonsistent state in which the kernel version does not match the modules? How can I proceed the installation from the downloaded packages?

  • Tp_smapi on Thinkpad T440

    - by user2597381
    I have a Thinkpad T440 with Ubuntu 14.04 (using i3wm). I have had trouble installing tp_smapi. I successfully installed it with dpkg -- can't remember whether I used apt or just downloaded it somewhere -- but I can't load the module. When I use modprobe on tp_smapi, I get this: "modprobe: ERROR: could not insert 'tp_smapi': No such device or address" Note that this is different from the error I get when I mistype the module name. I read somewhere that I might have to rebuild my kernel for it to work, but I'd thought that the kernel I was using (3.13.0-24) had that already set up. Has anyone gotten it to work? I hate how Lenovo manages the batteries!

  • Boot splash broken by "SP5100 TCO timer: mmio address 0xyyyyyyy already in use"

    - by mogliii
    I have ubuntu 11.04 with all the latest updates. I have an ATI HD 4350 graphics card and the "ATI/AMD proprietary FGLRX graphics driver" activated. The reported behaviour does not affect the functionality, its just an optical thing. When I booted up using the desktop CD, the ubuntu boot splash was shown correctly in high resolution. Now after installation with FGLRX the dipsplay is broken (see picture). http://img824.imageshack.us/img824/7269/tcotimer.jpg This is what can be found in dmesg [ 8.621803] SP5100 TCO timer: SP5100 TCO WatchDog Timer Driver v0.01 [ 8.621967] SP5100 TCO timer: mmio address 0xfec000f0 already in use [ 8.622650] fglrx: module license 'Proprietary.

  • HP 655 Notebook (Ubuntu 12.04) wireless internet disabled after running updates

    - by Bastian
    Today the update-manaeger suggested that I should download some updates. So I did. After the updates were installed I had to reboot the system. After the reboot my notebook doesn't see any wireless networks. I was looking for a long time on the internet for answers but non of them applies to my case. I have the idea, it has got something to do with the kernel I am currently using (Linux 3.2.0-55). Is this one new for Ubuntu 12.04? When I boot my system I can choose to use an older kernel (linux 3.2.0-32). When I use this one the notebook does see the wireless networks. This is my network card according to the command lspci: Ralink corp. RT3290 Wireless 802.11n 1T/1R PCIe Anyone an idea to fix my problems with wireless internet?

  • VMPlayer does not flush all outputs to serial port

    - by eddyxu
    I am debugging a Linux kernel in the VMPlayer on Ubuntu 12.04 configured a serial port to a file to see the debug information. However, each time when the kernel panics, only the backtrace stack were printed out instead of all the booting messages. This does not happend on VMPlayer Fusion. My .vmx file: serial1.present = "TRUE" serial1.fileType = "file" serial1.fileName = "~/tmp/serial.out" serial1.startConnected = "TRUE" msg.serial.file.open = "Replace" serial1.yieldOnMsrRead = "TRUE" My /etc/default/grub: GRUB_CMDLINE_LINUX_DEFAULT="quiet" GRUB_CMDLINE_LINUX="find_preseed=/preseed.cfg noprompt console=tty0 console=ttyS1,115200n8" How could I flush every message to both tty0 and ttyS1?

  • 12.10 update-manager is behaving strange?

    - by dschinn1001
    First I tried to update Kernel ( with 3.5.0-18 of your choice ) with update-manager. But update-manager crashed each time after 3 attempts when I typed my password ? Then I tried to update with terminal and apt-get as usual way. There then seems to be no update-files with a sudden after a pause --- Yes update-manager behaved strange, but it seems, that update-manager made a QUIET update ? There was nothing to see . . . I restarted my machine and new kernel is installed then.

  • How to hide process arguments from other users?

    - by poolie
    A while ago, I used to use the grsecurity kernel patches, which had an option to hide process arguments from other non-root users. Basically this just made /proc/*/cmdline be mode 0600, and ps handles that properly by showing that the process exists but not its arguments. This is kind of nice if someone on a multiuser machine is running say vi christmas-presents.txt, to use the canonical example. Is there any supported way to do this in Ubuntu, other than by installing a new kernel? (I'm familiar with the technique that lets individual programs alter their argv, but most programs don't do that and anyhow it is racy. This stackoverflow user seems to be asking the same question, but actually just seems very confused.)

  • nvidia-package in 12.10 somehow not same like in 12.04 resp. X-lib not complete?

    - by dschinn1001
    Not knowing if this has to do with new kernel-update automatic done by ubuntu 12.10 ? it seems that kernel 3.2 in 12.04 has not these problems with nvidia-drivers ? I tried to install the actual google-earth as deb-package with dpkg -i it seems to be no problem, but when I type command: google-earth in terminal, there comes up the report among else: Xlib: extension "NV-GLX" missing on display ":0". Xlib is installed completely and nvidia-driver is de-installed (then reboot) then re-installed again. the report of google-earth stays the same: Xlib: extension "NV-GLX" missing on display ":0". ubuntu 12.04 was working quite good with google-earth. however: bumblebee seems to be taken out of program ? ( or needs to be re-edited ? ) Don't hurry too quick with solution, I can wait !

  • Boot prompt hyphens

    - by purjuntu
    Booting an Ubuntu DVD, pressing F6 and then ESC presents the boot prompt with the default kernel options, with the possibility of editing and adding extra options. Something like: kernel /casper/vmlinuz boot=casper quiet splash -- Questions: What's the meaning of the two hyphens? When adding an extra option (such as "toram" or "vga=791"), is there any difference between adding it BEFORE or AFTER the hyphens? When typing commands in Bash, two hyphens in a row means "options end here; anything that follows should be treated as an argument, even if it starts with a hyphen". But the hyphens must have another meaning at the boot prompt, as "toram" or "vga=791" really are options.

  • High CPU usage when running a CentOS guest in VirtualBox

    - by sagi
    I am running CentOS 5.3 as a VirtualBox 3.0.0 guest running on Windows XP. The Windows host CPU usage is constantly at 50% although the CentOS guest is completely idle (i.e. 0.00 load average). I know this is a common problem related to the 1000Hz frequency that the CentOS kernel runs at, and previously a special kernel-vm packages were released to resolve the issue. However, these packages are out of date and the README says that they are not not necessary as of CentOS 5.3. I found out that there is supposedly a kernel parameter divider=10 that reduces the frequency to 100Hz with the standard kernel but it doesn't seem to have any effect when running inside VirtualBox. Is there any way to resolve the issue without resorting to a custom kernel?

  • Unattended grub configuration after kernel upgrade

    - by bouke
    Today I have been working on automatic deployment of an ubuntu server. I got stuck on automatic updating of the server using apt-get upgrade trying to upgrade to a new kernel. The log looks like this: Setting up linux-image-3.2.0-24-generic (3.2.0-24.39) ... Testing for an existing GRUB menu.lst file ... found: /boot/grub/menu.lst (...) Then a question is presented: Package configuration +---------------------------------¦ +---------------------------------+ ¦ A new version of /boot/grub/menu.lst is available, but the version ¦ ¦ installed currently has been locally modified. ¦ ¦ ¦ ¦ What would you like to do about menu.lst? ¦ ¦ ¦ ¦ install the package maintainer's version ¦ ¦ keep the local version currently installed ¦ ¦ show the differences between the versions ¦ ¦ show a side-by-side difference between the versions ¦ ¦ show a 3-way difference between available versions ¦ ¦ do a 3-way merge between available versions (experimental) ¦ ¦ start a new shell to examine the situation ¦ ¦ ¦ ¦ ¦ ¦ <Ok> ¦ ¦ ¦ +----------------------------------------------------------------------+ The desired outcome would be to select the first option and to continue: Replacing config file /run/grub/menu.lst with new version Updating /boot/grub/menu.lst ... done After running the upgrade by hand, I used debconf-get-selections to inspect the correct answer for the question (see other settings). It seems like update_grub_changeprompt_threeway is the question that should be answered. However, setting this using debconf-set-selections presented me with the same question: debconf-set-selections <<< "grub grub/update_grub_changeprompt_threeway select install_new" apt-get -y dist-upgrade How can this question be automated?

  • Screen going black, further investigation reveals healthy ram and hard disk, and several kernel oops logs

    - by Virulan
    Six days ago, I went to go take a shower, and I suspended Ubuntu as usual, to save battery life. I came back, and the screen was black. REISUB and general fiddling around did nothing. Restarted, and still had nothing on the screen. Since then, this has happened several times, and the only fix is to 1) force shut laptop, 2) take out battery, 3) hold power button, 4) put battery back in, 5) boot. I have investigated further into the matter, doing a ram test and a hard disk check. Both turned out fine, but then my attention turned towards the error messages I was receiving upon bootup, the whole "System program problem detected" dealio. I did some digging and found four kernel oops logs in my /var/crash. What I can understand of them points to two things, 1) they are connected to my suspending problems, since there are four them (I have had four suspending crashes), and they both confirm that there was a issue with waking up from suspend, and 2) the crashes might have to do with Python (possibly could be jumping to conclusions), since mentions of Python are peppered throughout the logs. At this point, I am unsure of how to continue, and I have come here for help. Is there any way I can fix this? Should I start by uploading the logs here?

  • 13.04 Temp Save, rt3290, Kernel downgrade

    It's kind of a multiplying but I didn't wanted to open more than one topics. I'd have a fresh install of Ubuntu with tlp configured and using acpi_call to keep 7670M turned off.

Another issue is my wifi card, rt3290: The rt2800pci module is fine and all that but the download performance is pretty bad alongside of annoying signal range and the prop. driver gives a conf error about some specific rt2860 code and integrales in pci_dev file. If I blank off the error making variables, module loads but the driver is unused. Since the driver is old, I was thinking of downgrading the kernel of raring to 3.7 or may be 3.6. Should &-or can I?

  • Upgrading Ubuntu(32 bit) 10.10 -> 11.04 fails and causes a kernel panic on boot

    - by Ubuntu Upgrade
    On Ubuntu 10.10 machine Upgrade to Ubuntu 11.04 using the update manager. The upgrade fails and leaves the system in an unstable state. When I reboot the system I get a kernel panic on boot. The error points to /opt/abc/runtime/lib/libc.so.6. By researching on this I found that there is a third party software abc causes problem. It has it's own runtime(libc) library. In /lib/ directory there is a link file /lib/ld-abc.so.2 ---/opt/abc/runtime/lib/ld-linux.so.2. If we rename this file to /lib/abc.so.2 or remove this file the the upgrade is success.

  • How are the concepts of process and threads implementated in Linux kernel?

    Can any one explain how are the concepts of process and threads implemented in Linux kernel ? I am looking for an intuitive explanation with some C snippets ( and important data structures) that clearly distinguishes between the two. I am just looking for the key implementation ideas I should get hold off. Essentially, I want to understand them and implement something similar in an embedded target (not supporte by any OS) in C language.
