Hi dave, yes i have installed this system with the option inst.text
I can try the option nomodeset in my next setup tomorow. Its the same hardware :-)

When i have no network, its easy to setup :-)

Thanks for all, have a nice day

Graphic-wise, if you must have video output, you may have a bit of a road to travel for obscure monitor and video card drivers. Luckily, ClearOS is meant to operate headless, so if you can get the IP address off of the server, skip the pain and torture and just use the web interface. You can find the IP address by using CTRL+ALT+F3 to switch to the F3 console. Log in as root and run:

ip address

This will show your your ip addresses if your box is on DHCP. Simply put that into your browser and go to town.

If you need to manually set up a static IP address, you can modify the appropriate NIC file in /etc/sysconfig/network-scripts/ifcfg-NICNAME using 'Method 1' here:

You can also do the install in text mode with no video. Parameters to try on the grub line are:

nomodeset

and/or

inst.text

Worst case scenario, you can install via console over serial.

I've dug out some old posts about configuring x11/xorg:

https://sfj48-fkj200.heiksthsd.cf/clearfoundation/social/community/graphics-resolution-of-local-graphical-console
https://sfj48-fkj200.heiksthsd.cf/clearfoundation/social/community/howto-configure-your-webconfig-x-resolution
https://sfj48-fkj200.heiksthsd.cf/clearfoundation/social/community/blank-screen-after-clean-install-no-login

The first one indicates you may need to create your own xorg.conf before you can adjust it.

Do you know if your card supports 60Hz? I think you only need an 800x600 display for ClearOS but I'm not sure.

Oddly, when I had the issue it was with a relatively recent Core I-3 processor with integrated graphics and an oldish 1024*768 LCD monitor when installing 6.x. The same combination works fine on 7.x.

hm i think thats my old graficcard :-) ATI Range XL and this has default 48Hz.
So i must find a old CRT Monitor :-)

I have try to install the ati-drivers but still not work.

Hi to all,
ok i have try this: as root

# GRUB_GFXMODE=1024x768x16
# GRUB_GFXPAYLOAD_LINUX=keep
# grub2-mkconfig -o /boot/grub/grub.cfg
# reboot

i can login in the red text box, after this F2 and there is coming the same issue.
So the bootparameters are ok but the resolution of Clearosapi or X11 is

Maybe since the vga= method was deprecated a while ago, it has now been removed from the kernel.From one of the links I used, instead, please try setting the lines:

GRUB_GFXMODE=1024x768x16

GRUB_GFXPAYLOAD_LINUX=keep

after you interrupt the start up process.

Hi Rick, i have successfully installed clearos by using the text install, so i can also login to the text console.
But when i start the F2 optin after login, is the monitor out of range, i have try the 'vga=791' and 'set gfxpayload=1024x768x16' but still the same issue.

You are virtually back to where you started, but you've done the installation. Now try to insert the vga=791 during start up or even try 788 for 800*600, 16bit. Don't worry about the API. It should follow - or mine did when I had the same issue with 6.x years ago.

Hi, hm can i change the ClearOS API resolution ? The login is in text mode and when i login to the graficalkonsole with F2 is the resulution out of range !!!!

ok i have installed this with install.text option and its fine.
So i must change the resulution of the ClearosApi on the server.
I reply later ......

Hej Nick, thanks i try it :-) Have a nice day

I presume you meant 1024*768?

See this post for interrupting the boot. On the linux/linuxefi line, try adding vga=791 (16-bit colour) or 773 (8-bit colour). This is method is deprecated but probably still works. If it works for you,then you have to make it permanent by changing grub2 as this only changes it for the one boot.

The preferred method is using something like "set gfxpayload=1024x768x16" higher up the boot options and it would be best to use this when you regenerate grub2 if the vga=791 works.
