  • Ubuntu Lucid: Erratic screen behaviour after boot

    - by fgysin
    In short: about 50% of the time I have a screwed up monitor setup after reboot. About 50% it is totally correct. Now the longer version: I updated my machine from 9.04 to 10.04 (via 9.10). At first I run into some monitor problems (I have a 3-monitor setup) because of the known bug in the new xserver driver for xinerama. This messes up behaviour if the mouse goes either left or above the screen number 0, i.e. I had to make my left-most monitor screen 0. Everything worked out fine finally, I got my 3-monitor setup back with xinerama enabled to get one big desktop streched over 3 screens. Now the fun part: Every time I start up my machine only one of the 3 monitors gets a signal and is woken up: it only recognizes the left-most monitor (screen 0) and crams all the desktop stuff into this one screen. If I go into nvidia settings I only see one physical device although all 3 are connected and have power. When I look into the xorg.conf I can still see my old setup with 3 devices, 3 screens, xinerama active etc... But I was totally unable to get 3 montitors to work. (I tried unplugging monitors, reconfiguring whole nvidia setup, ...) But it gets even better: When I restart my machine (i.e. choose the restart option from the Ubuntu menu) it shuts down and tries to restart. The restart then gets stuck after showing the Ubuntu splash screen with the 'loading bar' (the moving dots thingy) and I am forced to kill the machine by cutting power. But after the power cut the machine boots up normally and suddenly I get my 3 monitor setup back up working. That is until the next time I shut down and start up, where it all starts over again and I only have one monitor... (see above) I really have a hard time seeing where the error is. It must be that the restart boot somehow differs from the 'normal' boot. But the fact that it gets stuck and I need to cut power which then basically triggers a 'normal' boot does not really support this theory... My setup (please tell me if you need further info): 3 monitors as 3 screens as one desktop (with xinerama) 2 nvidia cards where screen 0 and 1 are on card 0 and screen 2 is on card 1 Ubuntu 10.04 Lucid Lynx (updated from 9.10, 9.04, ....) I would appreciate every idea on the subject, at the moment I really don't have any clue what to do...

  • LTSP keeping sessions active whilst turning off thin clients

    - by map7
    I'm using LTSP on a Ubuntu 10.04 64bit box with 8 thin clients. I would like to save power by automatically turning off the thin clients at night, but I would like to have the ability to resume the staff's session in the morning. Is it possible to keep a session running whilst turning off the LTSP thin client and resuming that session when you power up the thin client the next time? Could this work if you login to another thin client in the morning and resume your session?

  • HP DX5150, MS-7050 v. 1.3 Motherboard front panel pin connectors

    - by Daniel
    I recently purchased and installed a MS-7050 v. 1.3 motherboard into a regular non-HP case and thus the front panel connectors are different than the original OEM connectors which are all bundled together. The HP support website does not have this information available and someone from HP indicated in response to a support forum question that this information is not available. What is the motherboard pin schematic for the front panel i/o connectors (power, reset, hdd led, and power led)?

  • usb mouse connecting and disconnecting randomly and often

    - by Kalec
    Yes, I know this question has been asked here before but I can't add to the discussion over there and it did not help me, so here goes nothing. I've bought an acer aspire 5742G about 2 months ago or so and it's been running great, but sometimes I used to hear the windows error beep but I had no idea what was causing it since the "bug" was automatically fixed so fast I couldn't even see an error message (also it kinda always happened when I was busy also, either in a game or while doing my homework). Later on my mouse would simply not work for 3-5 seconds then work again, I thought nothing of it at the time. I also had a problem where it only worked in one usb and one only ... to move it I had to remove the battery, unplug the laptop and hold the power button for 2 minutes to reset the bios settings. Since today though it went nuts ... sometimes it disconnects / reconnects 12 times in 10 seconds and windows just keeps beeping till I unplug it, then it runs smooth for 5-6 minutes then it goes nuts again. Other times it seems like it skips (disconnects for a fraction of a second) other times just for 2-3 seconds. But this is incredibly frustrating. Sometimes the power just goes down (the laser turns off) and well that at least I would understand but this is a rare occurance. Now I know the usb ports work since I have a lot of other devices connected and I tried the mouse on a room m8's laptop so the mouse also works. My only conclusion is that it's an operating system / settings bug and / or problem (I have tried the mouse in all ports by the way). All drivers and bios are up to date (maybe except mouse but i can't seem to update that and the mouse has no name, just a serial number which helps with nothing. Still it worked till today and nothing should have changed any way). I have made sure windows can't shut it down to save power (in device management). Also I tried to delete the drivers and re-install them, rebooting and the power button trick but nothing ... most I have done is get rid of the 12 discconnects / reconnects every 10 seconds :) but that's all :( I would buy a new one but I'm afraid it might do the same thing :| ****EDIT****** Tried the mouse again at a friend but now it didn't even install it's software nor did the update work ... think I'll just buy a new one but I'd still like a suggestion at least so I'll leave this open

  • Easy Install Resets Hardware Settings

    - by bob5972
    I think there's a problem with the Easy Install setup. I selected "Installer disc image," and it came up and said that it would use "Easy Install," I think I hit next, and then I went back changed my mind, and selected "I will install the operating system later." After finishing the wizard, I think it still went and ran Easy Install, because it auto-installed VMware tools and I never got to select anything for my windows setup. Then, when it was finished, all the hardware changes I had made were lost. The RAM was changed from 2 GB back to the default of 1 GB, my CD ROM drive was set back to "Use a Physical Drive" and "Connect at Power On", and the Floppy Drive was also set to "Connect at Power On", after I disabled them. I was trying to install Windows 7, and I wasn't sure if I could change the RAM settings after installation without needing to reactivate it, so I deleted the VM and tried to start over. This time, the "Installer disc image" had my Win7 image pre-selected, so I clicked "I will install it myself later," set my hardware again, and tried to boot off my CD. Again,it did an Easy Install, and reset my RAM and my drive settings. So I deleted it again and the third time it still had the Win7 image pre-selected, but this time I unplugged all the drives and let it try to boot off the empty harddrive and fail, and made sure it kept all my hardware settings. Then, I powered it off, put my Win7 image in the guest CD ROM, and powered it on. This time it finally let me run the installer and pick my language, and type a user name. This time when I powered it off it kept my hardware settings. I can duplicate the error by doing exactly the steps above. Creating a new VM, selecting my "Installer Image," hitting next, going back, selecting "I will Install it myself," and then finish the wizard, and customizing my hardware right before the end, setting the CD Rom drive to the same installer media, and setting "Connect on Power On." (If I start it without the CD ROM in the first time, it doesn't do it). When I power on, I'm not prompted for any install information (like language and user name), and when it runs the first timemy hardware choices are reset (like the RAM back to 1 GB). If it helps, I'm running VMware Workstation 7.0.1 build-227600 on Gentoo Linux

    Since I seldom use the built-in cd-rom, but usually carelessly press open door button which is on the side of laptop. Is there any way to power off cd-rom so the button won't work. Better not to open the back lid and unplug power cable.

  • Restarting an IBM BMC without restarting the server itself

    - by SRobertJames
    I have a few servers with IBM BMC (Baseboard Management Controller). I'd like to power cycle the BMC without restarting the server. Is this possible? How? Note: On one of them, the web interface is down; so I'd need to either do this by physically restarting the BMC (not sure how to do this - even the power button on the server isn't supposed to recycle the BMC, I believe) or via the UDP or SNMP interface (again, not sure how to do that either)

  • Is Tripp Lite a trusted brand for a UPS?

    - by David
    I am looking to buy a rack mounted UPS that can take in 208V power and serve up 120V power. A basic APC unit that can do this is $4k. I have found a Tripp Lite model that will work for $2.5k. Is the extra $1.5k for the APC just for the brand? Or will the Tripp Lite serve me just as well? Thanks!

  • Poor performance of single processor 32bit Windows XP xompared SMP in VBA+Excel

    - by Adam Ryczkowski
    Welcome! On many computers I experienced poor performance of 32 bit guests running on 64 bit Linux host (I used only the Debian family). At last I managed to collect benchmark data. I made the benchmark by running custom VBA macro, (which we use in our company) that generates 284 pages long Word document full of Excel Pie charts, tables and comments. The macro is run as a single task (excluding the standard services) on a set of identically configured Windows XP 32-bit systems. I measured the time (in sec.) needed to perform the test. The computer (i.e. my notebook Asus P53E) supports both VT-d extensions and native Windows XP. It has 2-core processor, each core is hyperthreaded, so in total we have 4 mostly independent execution units. I use the latest VirtualBox 4.2 and VMWare Workstation 9.0 for Linux, installed together on the same host (running Mint 13 Maya) but never run simultaneously. The results (in column Time) are no less accurate than ± 10% Here are the results (sorry for the format, but I couldn't find out a better solution for tables in SO): +---------------+-------------+------------------------------------------------------+---------+------------+----------------+------+ | Host software | # processor | Windows kernel | IO APIC | VT-x/AMD-V | 2D Video Accel | Time | +---------------+-------------+------------------------------------------------------+---------+------------+----------------+------+ | VirtualBox | 1 | Advanced Configuration and Power Interface (ACPI) PC | 0 | 1 | 0 | 1139 | | VirtualBox | 1 | Advanced Configuration and Power Interface (ACPI) PC | 0 | 1 | 1 | 1050 | | VirtualBox | 1 | Advanced Configuration and Power Interface (ACPI) PC | 0 | 0 | 1 | 1644 | | VirtualBox | 4 | ACPI Multiprocessor PC | 1 | 1 | 1 | 6809 | | VMWare | 1 | ACPI Uniprocessor PC | | 1 | 1 | 1175 | | VMWare | 4 | ACPI Multiprocessor PC | | 1 | 1 | 3412 | | Native | 4 | ACPI Multiprocessor PC | | | | 1693 | | Native | 1 | Advanced Configuration and Power Interface (ACPI) PC | | | | 1170 | +---------------+-------------+------------------------------------------------------+---------+------------+----------------+------+ Here are the striking conclusions: Although I've read in the VirtualBox fora about abysmal performance with 32-bit guest on 64-bit host, VMWare also has problems compared to native run, still being twice faster(!) than VBox. Although VBA is inherently single-threaded, the Excel calculations, which take much more than a half of total computation time, supposedly aren't. So one would expect some speed gain when running on 2+ cores ("+" for hyperthreading). What we see is a speed loss. And quite big one too. For the VirtualBox the VT-d extension isn't a big deal. Can anyone shed some light on why the singlethreaded Windows kernel is so much faster than the SMP one?

  • What happened to my EEE PC keyboard?

    - by etheros
    I was using my EEE PC 1000H running Windows XP and out of the blue, the keyboard stopped working - pressing keys does absolutely nothing. It does not appear to be a hardware issue, as I am able to enter BIOS configuration with no issues. I've tried: 'Safe mode' 'Last known good configuration' Reinstalling the generic keyboard driver Removing all power sources and holding down the power button, as suggested by popular forums. What could the problem be, and what could I try?
