Fedora Core 3 Installation Question
Hey everyone,
I just started using Linux a couple of days ago (SuSE Professional 9.1) and like it a lot. After some recommendations from others I decided to give Fedora Core 3 a try. The install went extremely smooth, I am dual booting with XP and have no problems. After installing I did the updates and it downloaded a newer version of the kernel. But my boot menu at startup now has several entries, and looks like this: Fedora Core (2.6.9-1.681_FC3) Fedora Core (2.6.9-1.681_FC3smp) Fedora Core (2.6.9-1.667smp) Fedora Core (2.6.9-1.667) Windows XP Home Edition Does Linux allow you to run different versions of the kernel on the fly? I was assuming when I updated it, that it would take the old out and put the new in. This doesn't seem to be the case. Would it be ok to just edit my "grub.conf" file and remove all the entires except "Fedora Core (2.6.9-1.681_FC3smp)"? Or is there a process for removing old versions of the kernel? Any help would be appreciated I don't want to break something and have to re-install. Thank you. |
rpm -q kernel
then from that list, remove any kernels you do not want. everything else is taken care of. and yes, you can choose different kernels at bootup. HTH, Samsara Edit: It's also okay to edit the grub.conf by hand, but in this case, the easy way is to remove the superfluous kernel packages. |
When I type that command you gave me, this is what I get...
kernel-2.6.9-1.667 kernel-2.6.9-1.681_FC3 And then back to the command prompt... does this look right compared to the menu I have, and it doesn't give me an option to remove anything? By the way, do you know where I go in Fedora Core 3 to change my monitors refresh rate? It seems like it's not optimal, maybe I'm just really used to Windows XP but it seems a tad on the fuzzy side. Any ideas? |
Refresh Rate for your Monitor...
To change the monitor refresh rate:
From within KDE... Right-Click on your desktop "Configure Desktop..." "Display" (from the iconic choices in the left panel) "Size and Orientation" tab should be the third combo-box down. You will then need to log out then back in (to restart X). Apexdv :D |
Sorry, I forgot to say, you want to do
rpm -e kernel-2.6.9-1.667 to remove the older kernel version. It will probably suggest to remove the smp (symmetric multiple processor) things as well. You don't actually need these if you only have one CPU. Regards, Samsara |

Well, I believe I am the GNOME desktop and not KDE. I have a Samsung SyncMaster 171v and am running at 1280x1024 60hz. According the the manual this is optimal, although in Windows XP I ran at 1280x1024 70hz and things looked a lot sharper. Any other ideas? Thanks Samsara, that worked fine. I just have the newest kernel now when I issue the first command you gave me. |
Kernel Remove
Sorry, too...meant to say the same...

Re: Refresh Rate for your Monitor...
OK, I started poking around and found it, under "Preferences/Screen Resolution".
I can change the refresh rate there, but it only gives me the 60 Hz option under 1280x1024. If I go down to lower resolutions such as 1024x768 I can select 70 Hz. So, does anyone know how I can fix it to allow me the 70 Hz option? Monitor: Samsung SyncMaster 171v, Video Card: ATI Radeon 9800 PRO 256meg |
Refresh rate under Gnome
Wasn't sure abiut a GUI in Gnome so did a quick "google" for it. However I did see this: http://www.linuxquestions.org/questi...04/06/1/187807
It is for Mandrake but should be quite similar. Google Search For Gnome Refresh Rate Im'a lookin! Apexdv (newbie here too) :D |
I looked up some stats on the Samsung SyncMaster 171v, and I don't think it can do 1280x1024@70Hz. The manual says it will do 1280x1024@60 though. I think this is a limitation of your monitor. Your monitor may advertise that it can support up to 76Hz, but that's only at lower resolutions.

Thanks Apexdv for your help! I guess my intent was someone reading might know right off the top of their head a fix. I could get off my lazy butt and Google just as easily as you. :D Thanks for your efforts tho it is greatly appreciated. I am really liking Linux so far in my very limited experience with it and am doing everything I can to make it my "everyday" use OS. Unfortunately I game a lot so I will have to keep XP around for that but it would appear I can certainly do all my other stuff here. The simple fact I am not running tons spyware and antivirus software right now as I type this to you is a miracle itself. |

Unfortunately my monitor is not in the list of available monitors so I had to select "Generic LCD Display 1280x1024". |
Okay...
Logged into Gnome and looked around...
From your Applications menu (with the little Gnome footie)... "Preferences" "Screen Resolution" There you can change your res and refresh rate... Apexdv :D |

Kinda slow on my response, I see...:o
Anyhow, yes, I keep Win 2K around too just for a few programs (work related and proprietary). Other Windoze programs, I run with Wine. Turns out I only have to boot into Win about 1-2 times per week now. Lovin' the Linux, here! Good luck and have fun... Apexdv :D |
Fixed Monitor Refresh Rate Problem
I fixed the problem I was having...
I looked up my Horiz and Vert refresh rates for my monitor, and then edited the "xorg.conf" file to look like this: Section "Monitor" Identifier "Monitor0" VendorName "Monitor Vendor" ModelName "LCD Panel 1280x1024" DisplaySize 340 270 HorizSync 30 - 81 VertRefresh 56 - 85 Option "dpms" EndSection After rebooting, I had the 75 Hz option available to select. Thanks for everyone who helped point me in the right direction! |
