I'm currently using an external screen with my laptop at home connected with a serial port. When I'm in X, my laptop display is automatically disabled, when the external screen is connected. Is there a way to do this also at boot time? Where do I have to configure this? Also I'd like to have my login shells on my external screen, when switching to them out of X.
View 2 RepliesI want to change the Boot sequence in Ubuntu 10.04.

But with 10.04 this returns a blank screen. I assume something has changed.
Few months ago I stood on my netbook running F11 and broke the screen. I don't believe there's anything else wrong with it as the lights and fans act as normal when I turn it on. I hooked it up to a monitor but it doesn't automatically display on the external screen. So I have a pretty odd and possibly quite difficult request. Any step-by-step guide of which buttons to press after turning the machine on, in order to get it to switch to the external display? I just need something along the lines of, press enter, tab, type password, enter, press alt-a, down, down, down, enter, tab, etc. Another possible solution, a very long shot, would be a boot disk that defaults to an external screen?
View 3 Replies View RelatedI have tried to connect my GMA500 based Acer 751 to an external dsiplay via VGA connection. I couldn't get the right resolution on the external screen (1920/1080) so I disconnected it and rebooted. Now there is only an "unknown" screen in the display menu. I have rewritten the xorg conf file per instructions for enabling GMA500 but to no avail - conf file looks right but screen is "unknown", low resolution and 4:3 aspect ratio, instead of 16:9. How to restore to laptop monitor - I think I can take from there to enable the right resolution.
View 4 Replies View RelatedJust did a fresh install of Natty B1 (previously had alpha 2).. I noticed this issue w/ A2, as well.. plugging in the exterminal monitor (via mini-displayport-to-vga connector) will do the following:
1) turn the screen on the laptop's display entirely black (but not turn it off).. i can move and see the mouse cursor.. but everything on the window appears to not rending or "painted" black..
2) external monitor never becomes active..
the only way to recover is to kill/restart X or reboot after disconnecting the extmon.. having extmon plugged in from boot produces the same results (and it doesn't seem to ever become active during boot up). sometimes this won't happen right away if i plug in the external monitor.. but opening the Monitors system prefs dialog will definitely cause (or detect displays) ,etc I waited to see if the issue would fix itself w/ the beta update, but it hasn't.. Any other 8,1 owners out there that can verify this issue? My (totally uninformed) guess is that it's due to differences in the display/gfx hardware and thunderbolt integration(?)
(I've seen a verification verifications of working-out-of-the-box.. but they were from 8,2 and 8,3 owners (which have discrete graphics cards))... If anyone's gotten this to work with some config stuff, I'd love to see that as well (since the wiki page for 8,1 says it works ootb). If someone could let me know where I should look to capture error output when the above issue occurs, that would be awesome.
Why is the Linux boot sequence is organized the way it is?Power on + BIOS runs hardware initialisation and self tests, LILO/GRUB etc... but why is it organised the way it is?Would I be right saying it is primarily for debugging purposes?

View 2 Replies View RelatedWhat's the best way to get a list of the start order of services from systemd? Yes, I've tried
Code:
systemctl --order
This looks like the output I would expect, except that if that list is the system service start order, then my system is hosed. I certainly hope that my system is not starting nfs service before all the /usr/export filesystems are mounted.
I tried
Code:
systemd --test --system
but that generates over 22 thousand lines of gibberish! I filtered that with
Code:
systemd --test --system | grep -- -> | grep Unit | grep -i service
And it's less gibberish, but it's ALMOST the reverse order of the first command, and still pretty crazy.Ultimately, I need to discover, and fix the order of the services started by systemd, because they were mangled during the upgrade from Fedora 14 I hope that "systemctl --order" is either not the real deal, or I'm reading it wrong. Because if it is, I'm afraid I have a huge problem to fix.
I have an image generator (IG) running 64-bit Ubuntu Linux, GNOME & the SAGE application all running through an NVIDIA Quadra FX4500-X2 (dual GPU). Had to install a new FX4700-X2 (and the latest drivers) because 4500's are unavailable. The computer works fine except but I cannot watch the whole boot up sequence on the same DVI port anymore.On the 4500, all video came out the lower DVI port of the GPU with the PCI-X connector (let's call that the "a" GPU). But on the 4700 card, the screens you see during boot are divvied up between the lower DVI port of each GPU. The POST screen through Ubuntu splash screen comes out the "b" GPU while the "a" GPU is blank. The SAGE Initialization page and SAGE Desktop comes out the "a" GPU while the "b" GPU is blank.
I logged in as root and looked for a GNOME menu allowing me to force all video through the same GPU & DVI port, but couldn't find anything remotely close. Any suggestions on where I can look? Technically this IG is working, but I want to fix this to avoid future wild goose chases. The system uses 52 of these IG's.
Is there any way to disable the escape sequence in screen, so the user can't escape and run commands? we have a program that runs under user "shop". We want to wrap it in a screen session, and use .screenrc to set it multiuser and allow the "dev" user to connect to it. Then, if the "shop" user loses his connection, the session will stay running, and then the "dev" user can attach to the session and end it. We want the "shop" user to be unable to enter any "screen" commands.

View 7 Replies View Relatedrecently sent up another computer as follows:Two sata drives. Windows 7 was installed on the first drive(sda)and booted successfully. This drive was disconnected ( I have had some installs where Unbuntu wipes out the existing C drive eventhough I am installing to D) and Ubuntu was installed to the second drive (sdb). At one point I had to rebuild the grup on the Ubuntu drive and was careful to make it installed on the Ubuntu drive. To my surprise when the PC booted up I saw the Grub menu with a menu entry for Windows. The Windows drive was always the primary drive before the Ubuntu install. I was planning on the Windows drive being the boot drive and using a boot manager to determine where to go from there. If I utilize the BIOS boot option (F12) I can boot each drive individually. I cannot in BIOS set a particular drive to boot - just a hard drive. Everything is working I am just curious why the primary drive does not boot first. IN BIOS the Windows drive is a primary SATA with a lower number that the Ubuntu drive which is listed as a secondary drive.
View 4 Replies View RelatedI am facing a problem with my AT91SAM9260 customized board. Board is almost same as the evaluation kit.
I could download the binaries ( Bootstrap-v1.16, u-boot-1.3.4, linux kernel 2.6.20) successfully to the DATAFLASH/NANDFlash in my board by using atmel SAM-BA tool with usb/serialport/jlink.
Here I describe the problem.
When I power up the board, boot strap is not jumping to U-boot location, in the normal boot sequence and board stuck with bootstrap.
But when I disconnect/connect the JTAG USB cable ( provided with SAM-BA ICE) , it's jumping to u-boot location and booting the board properly. I'm getting the same error in NAND FLASH also.
I have tried one more test case.I copied bootstrap binary at the flash location, [location which is specified for u-boot binary] instead of U-boot.bin (location: 0x8400 in dataflash), I got continous bootstrap debug messages in my console. [ So can I conclude SDRAM doesn't have any problem? ]
Bootstrap code or U-boot code ?
I connected an external 22" monitor to my new linux netbook and now I am trying to improve the display clarity. By shifting the "clock" monitor bar to 100 ,the letters were less faded but edges of my screen were lost (by zooming in). Can I fix that through Linux?
View 3 Replies View RelatedI have an Nvidia card and I am using ubuntu 10.04. Before installing the ubuntu nvidia restricted drivers, the boot screen with the ubuntu logo would cover the entire display area of the monitor. But now, after installing the Nvidia driver and fixing the display resolution of the boot screen with the Plymouth fix, the boot screen doesn't expand to fit the entirety of the monitor display area. How can I fix this? There is a good 2 inch off from either side of the display while booting.

View 3 Replies View RelatedI did a quick search of the forums and noticed that 2 LED's flashing indicates some sort of kernel panic, but what about all three flashing, one at a time in sequence? I'm doing diskless booting of RedHat 5.1 on this machine but I'm hoping the problem isn't related to that, and just something simple. The OS loads, and I get to the login screen (not noticing anything about kernel panics during boot), but the keyboard doesn't work and the three lights flash. It's not a GUI login screen, so I don't know if the mouse would work.

Since the yesterdays updates the boot process lasts terribly long of my Fedora 12 on a x86_64 system. It lasts about 10 minutes or longer. The strangest thing is that if I press keys (any of them) it goes faster (about 1 minute). There are no errors or other things which might be the reason for such a behaver.

View 5 Replies View RelatedI have been enjoying Fedora 11 for sometime, and decided to try Fedora 12. All in all it is working, but the boot sequence seemed much slower. I decided to use bootchart to examine the boot process on my old F11 and new F12 installations. The result show F11 booting in ~34 seconds, and F12 booting in ~57 seconds. Interestingly, the first 30 seconds show that only kthreadd, khelper, and ata/0 are running. CPU and disk utilization are both zero during this 30 seconds span, then all of a sudden everything starts loading, CPU and Disk utilization spike up, and ~23 seconds later I get to the login screen. I sent an email to Harald Hoyer about this, and to my surprise he was kind enough to respond. He suggested I check the BIOS to make sure I had disabled the floppy drive, which I did. The problem persists, so I was wondering if anyone here was having a similar issue and if so how they have dealt with it. I have blacklisted the floppy module (just to make sure)
View 5 Replies View RelatedI would like to know as to how to save a boot order sequence...In my desktop PC I have a gigabyte MOBO housing Pentium Dual Core processor...
Whenever I have to boot from an external USB , I have to press del at boot , go into CMOS features and change the Order of Booting 1-DVD 2 USB-FDD 3. USB-HDD 4. Local Hard Disk
The problem is that everytime I have to repeat the above to boot from USB...I am also confused between USB - HDD and USB - FDD...Some utils partition and use the USB like a HDD while it is not the case with FDD I guess
How do you freeze the boot order so that on inserting any USB / External HDD at boot , the system should give it the priority over local hard disk..
Also in Giga MOBO I noticed that there is no "generic USB" mentioned in BIOS...It lists the USB device by name say "Kingston Data Traveler " "Sandisk Micro" etc ....
What should I do to make the boot order permanent?

View 9 Replies View RelatedI am attempting to boot Ubuntu off of a USB drive. The USB drive was created via the USB creator in the .iso file dowloaded from Ubuntu. But for some reason when I go into my BIOS and boot from the USB drive, it spits out one line of syslinux and copyright information ending in "et al" and then a flashing cursor but doesn't go any further. I would provide a screenshot but that isnt an option at the moment with not being able to get past the first line of booting. Also, I have never used Ubuntu as this is my first attempt at running it and it is obviously not going the best.
