Hardware :: How To Identify "Multi Card Slot"
Jun 29, 2010
How to identify "Multi Card Slot" hardware? The computer is a Samsung N150 netbook which has an optional "Multi Card Slot". Contacts can be seen inside the slot so the option is presumably fitted. According to the N150 manual it can read SD, SDHC and MMC cards.
There's nothing I can identify as a "Multi Card Slot" reader in /var/log/dmesg or messages and nothing in lspci or lsusb output. I'm no expert on such card readers so the device might be there and I can't identify it. There is a UHCI controller but isn't that only for Firewire? I don't have any of these cards so cannot try booting with one plugged in until I can borrow one.
The reason for wanting to identify the card reader is that I'm building a kernel which only has support for the actual hardware. AFAIK the N150 has no PCMCIA devices so I'm thinking to drop that from the kernel. Is it likely that the card reader is supported via PCMCIA in a similar way to USB drives being supported via SCSI?
Here's lspci output
Code:
00:00.0 Host bridge: Intel Corporation Pineview DMI Bridge
00:02.0 VGA compatible controller: Intel Corporation Pineview Integrated Graphics Controller

I have an ATI Radeon HD 3300 on-board video chipset, and an ATI Radeon HD 4350 PCI card. What I want is to have both displays available from one mouse/keyboard. I want to play media on one and have the other as my main desktop.The problem is that with Xinerama enabled, KDE desktop effects do not work (KDE says XComposite and XDamage are not available, even though I explicitly enabled them as extensions in the xorg.conf file), and performance is quite bad. Without Xinerama enabled, performance is great, desktop effects work great, but there's a lot of trouble with full-screen video, and the KWin window manager does not apply in the second display (although I can run a second instance of KWin on :0.1).

My server has 1 - PCI-e 1x slot and 2 - PCI-e 8x slot. Can I plug a 1x sata card into the 8x slot? Will it work? or do you have to have a 8x card?

I have a dual boot HP laptop that has an SD/MMS/XD card slot as well as an Acer Aspire One netbook that has two card slots.
On my HP laptop the card slot works fine with Vista but is not recognised when I boot in to Ubuntu.
On my netbook the original supplied Linpus OS obviously recognised both slots, when I load Ubuntu only one slot is recognised.
I have a USB card reader for the HP and the Acer has two slots anyway

I've just installed the latest version of Ubuntu (11.04) on my Lenovo S10-3 netbook. Everything works just fine, except the mobile mobile broadband.
The system doesn't seem to recognize the (integrated) SIM card slot. The SIM card slot is already integrated (it's located under the battery). I can add a new broadband connection manually, but it still doesn't work (I can't select it from the available connections). If I open-up the additional drivers manager, it doesn't show me any available drivers.

Bought a couple new cards to do some bitcoin mining (just an experiment) and before I hook them up I want to know how to use p2pool. im not that good with ports and was wondering how to correctly configure it. I keep getting Bitcoin is downloading blocks errors.
Edit: Im also getting a low mhash rate of 1.5. Is this correct for a geforce 9400m? Im not too worried about it after I use these new cards. and is there a difference in using laptops vs a pci slot desktop video card?

I'm trying to boot an SD card on a notebook that does not have BIOS support for booting from the SD slot. Using various how-to's I've figured out how to add additional SD card modules to the initrd.img file on a bootable USB drive such that I can boot Linux installed on the SD card.
However, best I can tell, it loads the kernel and initrd.img from the USB and everything else from the SD card. What I really want is to load the necessary SD modules from the USB and then chainload the SD card such that whatever kernel is on the SD card is loaded instead. Is it possible to chainload to another bootable device after the kernel (with the SD module additions) has already been loaded?

F12 on my aspire one (A110, the original 8Gb SSD model) works well with only one significant problem.
Suspend fails; the screen fades to black, backlight stays on, macine stops responding to keyboard/mouse/powerswitch and just hangs (for at least an hour... longest I left it). Only thing that works is a 5 second click of death on the powerswitch. Plus an FSCK on at least one occasion after reboot. I have not been able to check if SSH and shutdown possible (on vacation) plus have logs go to a tmpfs (to save my SSD) so no log info. Similarly I cannot confirm if this affects hibernate because I run without a swapfile (SSD again, i.5Gb ram installed and I have never come even close to running out of memory).
But I think I have the culprit anyway:[url]
As described there; shutdown fails if there is a mounted card in the cardreader slot (/dev/mmcblk0) My system has a 4Gb SDHC card in the LH slot with a single XFS filesystem; which has my homedir on it; if I unmount that filesystem (but do not remove the card) shutdown and restore appear to work properly. But if the filesytem is mounted I get the bsod. Linked bug suggests this is restricted to large filesystems (?SDHC?) but I have not fully confirmed, although that matches my situation.
Posting here to see if anyone has any further info/workarounds, to ensure the fedora crew are aware that this appears to affect F12 (and is a regression, F11 suspended fine) and make sure it is documented somewhere. The linked bug also states similar bad suspend activity on other netbooks.
I'll try some other variations (and see if it also happens with USB sticks/RH cardrader, and report back here.

I have fairly new requirement for a second monitor. My main display is running fine using nvidia proprietary drivers.I do have a pcie (probably x16) video card sitting around, but my motherboard only has 1 x16 slot (used by my main display), 2 x1 slots and a few pci slots. From memory, the second video card is an ATI card.Questions:
1. Can I put a PCIE x16 card in a PCIE x1 slot?
2. Would using 1 Nvidia card and 1 ATI cause trouble?

can one ethernet card support multiple ip address? but i think it's very dangerous. if bad guy take many ip, other people can't get ip. "does one ethernet card take multiple real ip or multiple virtual ip(one real ip)?" if it takes multiple real ip, then how it works good?..

I have a dual monitor setup with a nVidia 7300 card. I'm not sure exactly when this started to happen, but it's happened for a couple of years at least. when I'm in one or the other monitor the cursor will sometimes "stick" in that monitor and refuse to go to the other monitor. it'll just 'wrap around' as when I go to the right part of the monitor, it'll then jump to the left side, and vice versa. Also once in awhile, if I'm in one monitor, the cursor will be taken away and put on the other monitor. I'm just now starting to see a few patterns on what's happening. It's worse if I have VCL playing in the left monitor, (my secondary), and I've got a program maximized in the right (primary) monitor. That's when it'll 'stick' on the right monitor. After I roll up the program or minimize it, then it'll free the mouse. But it's not instant. After it's freed, it still doesn't work exactly. If you click on any program on the left monitor, then you have to move back and forth before the mouse will work on the left monitor.
The second problem I'm having happens only on the secondary monitor. At times the precision is WAY off. For example, if I try to put the mouse right on an icon, and click it. It won't work. But if I move the mouse over to the right or left, suddenly the pop-up comment box pops up, the icon is highlighted and clicking will run the program. It can be off as much as 100 pixels! I've seen these problems in all sorts of GUIs; XFCE, DXCE, KDE 3.x (I never tried it in KDE 4.x since it was nearly unusable) and Gnome. Right now I've only see this on Ubuntu 8.04.01, to 9.10 (I never went past 9.10), and at first I thought it was X since all GUIs had problems. But someone now says that nVidia's driver might be to blame. If you can tell me what command to type in at the terminal, I can supply the current video driver's version.

I have a ati firepro v3700, and I installed the driver I think. I did the fglrx install, and it said it worked. I believe it because prior to doing that my video was off and very laggy, but now it's fine.
My problems are these: yast won't identify my card in the hardware section, and it won't let me turn on 3d effects. I know most people wouldn't care, and I wouldn't, except I use linux to do FEA and CFD research. I used ubuntu before no problem, but some of the programs I used weren't supported.

I'm trying to set up some scripts from one machine that I can use to remotely lock all of my workstations remotely. I have a virtual ubuntu machine ported out to the internet w/ ssh open and I'm using ServerAssistant on my droidX phone to kick off the scripts. I have all of my ssh keys shared between the boxes so I don't have to log on. Everything works beautifully for one machine, a regular Ubuntu 10.10 box with a single video card with 2 monitors. This is the script contents:
Code:
ssh -X brainstem@zappa "export DISPLAY=:0; gnome-screensaver; gnome-screensaver-command -l" But my other desktop, a triple monitor ubuntu studio 10.04 box (2 vid cards) will not kick off with the same syntax as above (obviously different computer name). If I execute the command manually from the remote machine, it doesn't work either. Just to make sure, I ran "gnome-screensaver-command -l" locally on this box just to make sure that part works - it locks the machine locally just fine. I just can't seem to get it to work from another machine. I've tried from 2 different boxes and have the same results. I can do anything else I want over ssh and it all works.

Anyone successfully using VNC client on a Mac to control a Debian server?I have the vncserver setup on the Debian machine properly. But I'm having problems connecting to it from both a PowerMac running Tiger and a MacBookPro running leopard.I can connect no problem from a machine running Slack12.2, have not setup port forwarding on my router to connect remotely yet.My Debian machine is running the latest stable release of squeeze with KDE4.I originally tried this with RealVNC Enterprise for OSX but I'm not gonna buy it so I need another alternative after the 30 day trial ends as they have no free version for OSX.
The situation is that I do freelance graphic design on the PowerMac with Cinema4D and Photoshop so I spend most of my time on that machine which is located in my home studio in my attic. Aside from the MacBook and a Dell desktop(family machine)all my other machines and network hardware are in the basement. So to go from the attic to the basement everytime I need to do something on another machine is not practical, and the only other machine I need to access on a regular basis is the Debian box in the basement, this makes the most sense.
I also have a 14 year old living in the house and he's fascinated by all this and will meddle in anything he gets the chance to so all the Linux machines and network hardware need to be behind lock and key.

Now that Ubuntu 10.04 has multi-touch capabilities built-in, if I do not have a multi-touch screen or surface device, can I get 2 USB mice and get 2 pointers on the screen? One for the right hand and one for the left hand as I am ambidextrous, and would find it very convenient to have 2 mice.

Im running 64bit centos 5.6 and using virt-manager.On one of my guest OS's, Windows 7, The max Physical CPUs is 2, you can have unlimited CPU Cores however. (like my machine i use for work has 1, 4 core processor).The issue im having is xen only allows you to set the vcpu arguemnet in your xen config file. How can i set it so that 1 CPU has several Cores just as windows would recognize this machine if i were installing directly to the hardware vs via a VM.Ive searched for 2 days staright trying to address this issue, very little progress, Does anyone know where a XEN support forum is? all i get is the citrix xen support forums.
here is the best info i have found on this, but i dont know how to change this for my CPU to work, when i enter this in my xen config it essentially ignores it and just takes the value of vcpu= so windows shows 2 CPUs each with ONLY one core. Id like 1 or 2 CPUS showing Several cores.The physical Hardware is 2x Xeon 5300 Quad Core CPUs.
> # Expose to the guest multi-core cpu instead of multiple processors
> # Example for intel, expose a 8-core processor :
> #cpuid=['1:edx=xxx1xxxxxxxxxxxxxxxxxxxxxxxxxxxx,[code]........

My friend recently bought a memory upgrade for another friend, when i was round at his house i tried to install it for him. Usually this thing is fairly simple, just plug it in and go.
The problem is the second ram slot appears to not be working. i have tried each module on their own in the first ram slot, both working fine. I tried them both on the second ram slot, the computer seems to fail POST, (no case speaker or LED display, but the screen stays black)
also, putting them both in has the same effect. sorry about the [DOT] & [SPACE] but the link is broken otherwise Motherboard: Gigabyte GA-945GZM-S2 -- www[DOT]gigabyte.com.tw/Products/Motherboard/Products_Spec.aspx?ClassValue=Motherboard&ProductI[SPACE]D=2467&ProductName=GA-945GZM-S2 RAM: (2x) Corsair VS1GB667D2 -- scan.co.uk/products/1GB-Corsair-Value-Select-DDR2-PC2-5300-%28667%29-240-Pin-Non-ECC-Unbuffered-CAS-5-5-5-15 User Manual: europe.giga-byte.com/FileList/Manual/motherboard_manual_ga-945gzm-s2_3.x_e.pdf
The clock rating on these modules are a little high for that board, but I thought they would automatically underclock at the very least for them to both work.
I tried to reset the CMOS, but couldn't find the jumper, so i just took out the battery for 5 mins, does it have the same effect?

I tried to install Fedora 10 with an encrypted root-filesystem on my Laptop. The problem was, that I wanted to install to the second hdd which resides in the extension slot of the laptop. I can either have the dvd-drive or the hdd in the slot. So I removed the internal hdd, and inserted the second one in its place. That way I could use the dvd. The installation went fine and I could boot into the OS. Then I removed the hdd again and inserted the original hdd to the internal slot, and the fedora-hdd in the extension slot. I can select during power-on from which hdd i want to boot, but I cannot boot fedora. After the first dialog, where I can enter the password to decrypt the disk, I get an error message (something like drive not found). I tried to change the grub settings in the /boot partition (which is not encrypted), but without success.
So, is there a way to boot the system? Or how do I install Fedora on the second hdd without the dvd-drive?

Can somebody tell me how to enable/disable a pci slot.I am trying to do a hotplug on the pci slot.Is it possible in Open SUSE? If its possible can somebody please tell me how to do it.I was doing some research and went over the following topics hwup, hwdown, sysfs, but nothing worked.My confidence on Linux OS is pretty high and am sure there should be a way!

Ever since I upgraded to 9.10 I have had 2 green slots on the panel at the top of the desktop. Both slots have a lighter green bar that oscillates back and forth. I attach a screen slot with he slots circled in red. Looking at other desktops posting on the forums I gather this is not normal but I cannot find what causes it.

A linux box equipped with LSI MegaRAID SAS1078 controller has 4 SAS disks slots. Slots 1+2 holds disks that have been configured (using the LSI bios interface at boot time) as raid-mirror array (hence exported by the controller as one unique LUN). Slots 3 & 4 each holds disks that are not configured as RAID ("direct attached devices" or "raw devices"). The "scan order" numbers for each disk, as reported by the controller interface, are in the same order than the "slot numbers".
Grub (installed on MBR of slot 1+2 LUN) sees:
* slot 1+2 LUN as hd0
* slot 3 disk as hd1
* slot 4 disk as hd2
The Grub boot command says:
root (hd0,1)
kernel /vmlinuz-2.6.16 root=/dev/sda3
initrd /initrd-2.6.16.img
(hd0,0) is swap
(hd0,1) is /boot
(hd0,2) is /
The linux distro is SUSE (SLES10 SP2). Grub boots correctly (disks in slots 3 & 4 are empty, even no partitions; and as expected, grub tab-auto-completes hd0 with available partitions; on the other hand, grub also sees hd1 and hd2 with the the tab completion, but eventually without partitions behind).
Now the problem: The kernel loads, initrd as well with its bunch of modules, and then harddrives are detected by the scsi driver and there I see: ...
SCSI device sda: ...
sda: unknown partition table ...
SCSI device sdb: ...
sdb: unknown partition table ...
SCSI device sdc: ...
sdc: sdc1 sdc2 sdc3 sdc4 < sdc5 sdc6 sdc7 sdc8 sdc9 > ...
Indeed, shortly after, the sysinit fails mounting FS (because FSTAB addresses directly /dev/sdaN and not UUIDs nor UDEV persistent names). Please note that I do not want to use UUIDs nor LABELs (for personal reasons it's no use to detail here). I tried to change the disk order at the LSI raid bios level, but:
* this interface cannot change priority for LUNs, only for raw devices (and these raw device priorities are set according to slot numbering)
* Grub indeed sees disks correctly, so I think the problem happens only at the linux stage, not earlier.
I tried to look at UDEV persistent rules (in the /etc as well as in the initrd.img/etc after a cpio extract), but there is nothing human readable (nor any obvious aliases, like those we can find for eth cards for instance). It seems that linux sees hardware raid arrays after raw disks, though raw disks are in farther physical slots (and with higher ordering number on the controler) and hence orders them incorrectly. And that's not the behaviour I expect, since I thought the hardware RAID LUNs were seen exactly as raw devices at the linux level, so raid or not should not make any difference in the disks order.
All this story is rigorously reproductible after several boot attempts (i.e. no random discovery here). Is it related to existing udev rules (default rules from SLES10 SP2) I did not find? Or to some missing udev rules (explicit aliases) I should have added? Or to some other udev mechanism I should get rid of (or even get rid of udev completely!)? Or to something else (not udev related... perhaps the fact I also have LVMs and software raid management...)?

I have an Acer Aspire One "netbook" that has 2 SD slots. If I insert and try to mount an SD card post bootup it can't detect the card (not listed in fdisk -l, and no messages generated to dmesg). Almost as if the slot isn't functioning.
The weird thing is, if I boot the computer up with the SD card IN the slot, it picks it up no problem, shown in fdisk as /dev/mmcblk0p1, and I am able to mount it no problem. I am also able to unmount and remove the card and the SD slot continues to function normally. Although I can boot up the computer with the SD card in the slot with no issues, I'd like to be able to have that "slot" active on boot even if I don't have a card in it.
A few more details, Im running slackware 13 with fluxbox wm.

from vuze(bit torrent client) it shows my total download speed to be 20.56 KB/s....while my network monitor tool shows a speed around 72.41 KB/s. Similar is the case with upload speed. In much simple words the download/upload speed that vuze shows appears to be less than that shown by the network monitor tool.I must mention that at the time vuze was running there was no other simultaneous downloads.I don't understand why this is so?Is there any tool that can give me the exact information of downloading & uploading speed or rather any tool that can give me the details of uploads/downloads presently going on.

We're using condor at work to have cluster processing of java jobs. I know how to tell condor to require that a given job should be run on a particular slot. You can put on the Requirements string in the submit file a "Name" value(s) -->
Example:
Requirements = ".. Name == slot1@host*.domain.net || Name == slot2@host*.domain.net"
Which would tell condor to only run that job on slots 1 or 2. But what I need next is some way to have condor modify the arguments string depending on the slot it used. Our condor blades have 8 slots per machine but only two CUDA Tesla cards per host, so I want to dedicate slots 1 and 2 for using the Teslas and slots 3-8 for not using CUDA.
My java code has a java '-D' property so I can tell it to use CUDA or not, but then I
have to have a way to configure condor to append that to the job arguments if
the slot is 1 or 2 or not append it otherwise; So I want this arguments list passed for slot1 or 2
"Main.start -Djava.library.path=/usr/local/cuda/lib64 -Dcuda"
and this for slots 3-8:
"Main.start -Djava.library.path=/usr/local/cuda/lib64"
I don't want to just make the developers hack their submit files to put the
-Dcuda on the arguments line in combo with their adding the Name entry for
slot1 | slot2 because that seems error prone to me.
I want condor itself to add the JVM -Dcuda argument when it's slot 1 or 2 to reduce errors because these jobs take a long time and a mistake wastes lots of time.
