General :: Fedora 12 How To Specify Monitor Type On Bootup
Jan 15, 2010
I have a cheap usb kvm that doesn't pass the EDID data back to the computer from the monitor. And now Fedora 12 seems to rely on autodetection of the monitor to start up at the proper resolution. When I have my samsung 712N on the kvm, fedora 12 boots to only 800x600 max resolution. If I connect the monitor directly to the computer video card, fedora sets the screen resolution to the desired 1280x1024 properly.
When booted through the kvm, fedora won't let me detect or select the correct monitor, and I haven't found any way to work around the problem other than pulling the monitor off the cable, connect to the cpu, reboot. After it's booted I can reconnect the monitor to the kvm and the video is fine.
My question is does anyone know how to manually tell Fedora 12 at startup what kind of monitor I'm using and skip the bootup monitor detection? So far I've spent a couple unproductive hours with google to discover this isn't a totally uncommon problem and no site I've found seems to have any solution.
OS: Fedora 12 Video card: ATI Radeon 9200 series Monitor: ViewSonic 19"
I installed Fedora 12 configured Gnome automatically. Generally default settings. My monitor was connected directly to the video card and all was good. My video card was detected and my monitor was detected as ViewSonic Corporation 19" and I can set the screen resolution to 1280x1024. I had no xorg.conf file, as it seems that Fedora 12 does a great job of PnP to just set everything up.Now I go and complicate things by hooking up my monitor through a KVM switch. All of a sudden my monitor is "Unknown" and the best resolution I can achieve is 800x600.
Sure, I could go and reconnect without the KVM, but I want to be able use it.Is it possible to edit xorg.conf to tell it "Trust me, just use 1280x1024 at 60Hz even though you can't figure out what the monitor is"?
I tried a number of the posted suggestions to generate xorg.conf files but none of them get me what I need. A simple sample file listing that does the minimum is greatly appreciated (I can experiment from there once I get a basic setup working).And can someone explain if it is X or the ATI driver that is getting confused by the unknown monitor type. It helps to know what is actually going on in addition to a fix (so I can figure it out myself in the future). Thanks!
I know the tool system-config-display can tell me all about my display but it's not available on all systems and so I'm looking for alternative ways to get my monitor type. Ideally, I could just look in /proc but I don't see anything there and I would like to be able to do so from a script perhaps written in bash or perl. Is there some place to get this info, say in a config file somewhere?
The problem is that when I select System -> Preferences -> Monitors, the monitor is shown as unknown and it only allows me to set 1280x1024 (shows 0Hz as display refresh rate) which is way too high for my brother. I was wondering if there's a way to select the proper monitor from a list so all display resolutions are shown and I can select a lower one for him.
I have been trying to put same type of items (rather icons) together, my concept is same like windows where I can put that by right click and--> arrange icons by --> group,So folder icons come together, pdf files come together etc etc and there is a separation between any two types of items (icons)Can I have that facility here too, I am using fedora 13, and when ever I rightclickunde arrange items --> name type size etc comesbut group by items is missing.Also here refresh option is missing, what we very much familiar in windows, I know that fedora is not windows, but I think this problem can be solved.
I've upgrade my fedora 11 to 12 by installtion DVD and everything is fine right now.Everything is there and the new system looks good.However,my boot screen is still the same with 11.How can I switch to the new screen?
I updated to the newest kernel today ( 2.6.31.12-174.2.19.fc12.x86_64 ) via software updates and noticed there is a 10 second pause just after the grub screen goes away and before plymouth comes up. This never happened with the previous kernel. Anyone notice this?
I want to play a video thru VLC player as soon as when system boots up. is it possible using crontab or any other way to go about it??? Also I want to play a file by telneting to a remote server (eg: the file is present is /media/disk/movie.mpg). is it possible to write a script and execute them using crontab.
I am facing bootup issue in Fedora 14.I troubleshoot the bootup issue i m facing probably because I have done change the name of volumes from disk utiltiy. I read somewhere that it should be done from another place (administration option, the last menu of fedora and there is some volume/disk management..like thing that give rod like blue/red picture of disk=>System-config-lvm) rather then disk utility under system tools. I think that my LVM path is not setup..due to rename of volume..it is mismatched somewhere...that includes path...finally using rescue disk i enter in shell prompt and mounted my system using chroot /mnt/sysimage then found that my /home is empty, so done some readings and found that using mount /dev/vg_brs/home /home i am able to get my home fixed that now appeared my user and whole data.
but that is till i m in shell prompt. Don't know where and how to fix/add this line so that boot loader of fedora will take this instead of something other that it is taking and not founding resulting in failure to boot with message (in between lines)
I have a pc with 1 GB RAM,Intel Core Duo CPU(1.86 GHz).Recently during formatting of the pc with new windows , I (accidentally)powered off the pc during the process.Due to which what has happened is there is no screen during the time computer boots up when switched on.Only when there is a login window,the screen becomes active.I even installed UBUNTU (which I am still using) on the whole hard disk but problem persists.The problem seems to be independent of the OS.
I am facing problem with the fresh installation of Fedora 11. (I have moved from Fedora 9). When I try to view videos on ..... or use the Cheese Webcam Booth, I get blurred lines on the screen and I am unable to see any video or pic.
Also I noticed that the when i go to System > Preferences>Display, it shows me UNKOWN MONIOR.
However, if I got to System>Administration>Display and enter the su password, it shows me correct monitor and the graphics driver.
I am not sure if my original is related to the Unknown Monitor.
I also tried to install Nvidia driver but it crashed the xserver and I had remove the driver.
My Monitor is LG 700E and Graphics card is from intel. as I am not able watch any video.
I am having problems getting my external monitor to work. When I plug in the monitor, both the laptop screen and the external monitor go black. When I unplug the monitor, the laptop screen works again. When I startup with the external monitor plugged in, neither screen works or teh computer hangs or something.
I have had the external monitor going on a couple of occasions. I did manage to configure my monitors through System Settings > Display. I turned off the laptop monitor as I just want to use the external. But after rebooting, things didn't work.
I have an external monitor connected to my laptop (extended display). I always drag the Totem player from the laptop screen to external monitor to watch video files. I wonder, if the Totem player can be set to open in the external monitor automatically, everytime I open it?
My software and hardware information are as follows. I have Fedora 12 and KDE 4.4.5 installed on a Dell Vostro 1500 laptop. I believe it's a 64 bit processor; it's an Intel Core 2 Duo CPU. The external monitor is a Dell as well.
My problem is that my system does not seem to be detecting an external monitor that I have connected. Everything else is working just fine; however, I would like to have the option of attaching an external monitor. When I plug the external monitor into the laptop, the external monitor remains black and appears to be in power save mode. The results of xrandr -q (with or without the external monitor attached: it doesn't appear to change) are as follows.
Code:
How can I get my laptop to recognize that the external monitor is even connected? Let me know if I can be more specific or provide additional details.
I had some problems and had to upgrade my motherboard. I chose the same manufacturer and haven't had any major problems booting into Fedora 11. (I was totally amazed by this BTW).The only thing is that I have 8 GBs of memory in my computer and System-monitor now says that I only have 3.2. Lastly my nvidia driver which is working correctly, is giving errors about python at bootup. Something about glib being presentAnother weird thing is that GRUB will not let me interrupt it either during normal usage nor with a live CD loaded. This also started happening after I installed Fedora 11 on my old board.
Sometimes, in fact quite frequently, when I boot up my system, PulseAudio does not work. ('Connection Refused'). If I log out of my normal account, log in as root, log out of root, and log back in to my normal account, this seems to reset Pulse Audio and it works again. Seems like a security glitch, but I can't be sure.
When I went to start up the computer, the kernel usually hung at the same place on boot up, although sometimes it booted just fine. The default kernel is 2.6.31.9-174.fc12.x86_64. It's boot up arguments are:
I also have kernel 2.6.32.7-37.fc12.x86_64, 2.6.31.6-145.fc12.x86_64, 2.6.31.5-127.fc12.x86_64. I have seen the same behavior out of all four of them. Last night I ran Memtest86+ all night. It took eight passes with no memory errors. As far as hard disks go, I have two Seagate Barracuda 1.5 TB drives operating as software RAID 1 (mirroring). One of the drives does have three bad sectors. The motherboard is an Asus P6T6 WS. This morning I plugged in the GP diagnostic chip that came with it, but I'm not seeing a whole lot useful there, except that now it is just displaying "FF" non stop.
I did some poking around on the web, and it looks like "FF" is supposed to mean that the CPU isn't properly seated, which makes no sense because the system monitor software is detecting all four cores perfectly, and I have no other odd behaviors anywhere else. At this point I'm rather at a loss to understand what could be causing the difficulties. Sometimes any of the four kernels boots fine, and sometimes they don't. The funny thing is that on the blue "boot progress bar" all four kernels hang at exactly the same spot if they hang at all. After doing some more poking around, I'm relatively sure that "FF" does NOT mean that the processor isn't seated correctly. I'm going to try contacting Asus and see how far I get towards getting some good info on what the diagnostic codes mean.
I've been able to get a laptop on Fedora 14 (2.6.35.6-48) working with a Netgear WNA1100 Once up and running, I execute "ifconfig wlan0 up" from root, and everything connects just fine and is stable as long as I stay logged in. But, I haven't found how to do this automatically on boot.
I've tried to use NetworkManager, but I cannot figure out how to get the GUI to show up - it says its running and enabled in the Services gui, but I haven't figured out how to actually use it! I checked to see if the nm-applet is running with ps, and for the user login, I see:
I'm not sure if the "sm-disable" flag is my problem, or how to change it. I'm not even sure if NetworkManager will allow me to set things up for bootup, but that is the path I ran down...
I assume this is a fundamentally easy process to set this up on bootup, but I'm not stumbling across the method. I recall doing this kind of thing years ago when I was an engineer, and before I got my lobotomy to become a manager...
I have a problem where the volume in F15 is way too loud. The computer is a Dell Optiplex Gx280 using what is labeled as an Intel ICH6 for the audio card. I have the system volume at about 10% and have to still keep banshee's volume at 5% or lower otherwise it's just too loud. The system saves the volume level between reboots, however I've run alsamixer and noticed that the headphone jack is at max volume.
So, I ran: Code: sudo alsamixer -c0 lowered the headphone jack volume by half, then ran Code: sudo alsactl store 0 to save that setting. Upon rebooting, the headphone jack is back to 100%, though.
If I run Code: sudo alsactl restore 0 then it will restore the settings I saved but it obviously isn't doing this during bootup. How would I run this command at boot?
I installed F11 on a SATA 500 GB Hard drive. I plugged this HD in various computers. It worked fine.
However, when I try it on the following platform (the one I have to get it to work): (PC104 bus, AMD 1.1GZ with 512 RAM), I get a file system error during bootup.
On the other hand, the system gave the chance to enter the root password. So, once I did this, I tried to run commands "fsck -f /dev/sda" and "fsck -f /dev/sda1". The command could not find sda or sda1.
I tried the fsck on different platforms (with the same HD), it worked fine.
I returned the CPU board to the vendor, and I am expecting a new board soon. I assumed the problem could be with the board itself. But, I am not sure.
We are brand new to the Linux platform and just learning. So this is what we have done so far, Installed RHEL 5 on a test machine. Says it was succesfully installed. But when it boots it boots to a blank screen with no prompt or gui or anything just a black screen. Does not accept any input or anything.
We are able to get into the GNU Grub and this is what we see
I can enter b for boot
We would like for this to boot to a GUI interface.
All of a sudden my production system changed to read only. Ran fsck and it ran for about 5-10min before it crapped out. Now when rebooting, getting an ext3-fs error, attached is an image. The system is on an ESX environment.
I just upgrade to F14 from F10 on a dual montor setup. Firefox behaives differently on F14 than on F10. On F10 it followed the mouse pointer's location and show up on the correct monitor
When maximized at close, it is always displayed on the left monitor. When not maximized at close it will open on the monitor where the mouse pointer is located.
About minimize/maximize Firefoxe before closing and it seems to work in some case, but not for me.
I am using Centos 5.4 and I changed the group on /dev/lp0 to group from root. After I do this my program printing directly to /dev/lp0 works fine. But when I shutdown and reboot the system the group on /dev/lp0 has changed back to lp. Does anyone know how to keep the group changed to group after a reboot.
Running Centos5 with the latest webmin, WHM and Cpanel.I am trying to run the following as a startup script through webmin, but so far no joy. Searched the internet for a couple of hours last night and couldn't find the answer.
I have Ubuntu 10.10 installed but when booting up the partitions are not visible on the boot loader. I have tried grub-install and update-grub off a live CD but to no avail, fdisk show the partitions still exist.
