Need function details for CentOS 7.3 install...

[Mike Krall]

I know little of Linux... less of CentOS/RHEL. I will install CentOS 7.3 (1611) GNOME-Desktop into multi-distro laptop with symlinked separate data partition... a simple, personal use, desktop machine.

Looks like this:

Code: Select all

:~$ sudo parted -l

I have both CentOS 7.3 LiveGNOME and CentOS 7.3 DVD1 on USB's. Have run on Live-GNOME and have been through install steps in both. I've questions/need clarification/need verification/don't understand things.

One thing at a time.

Firstly...

In CentOS DVD lead-up to install start, there is a running list of items. I see a flash of red... moves too quickly to read... have not found a way to stop the item-checking to view it. When booted into LiveGNOME USB, though Wi-Fi and Ethernet appear to be enabled, and web-site addresses show, the browser window is black, or black with white boxes, or white with no boxes. Mouse movement finds link areas. Clicking changes page in address bar.... same black, black-white-white. Entering new addresses moves page to new address... same viewing results.

ASUS F556 UA

:~$ lspci | grep VGA

Got CentOS-7.3 in multi-boot machine. It doesn't work well with other OS's. Booting to large screen and/or to "rescue". Work around is: 'Esc' key at ASUS startup screen... choose CentOS... pick first of 3 listed (.693)... picking .514 gets overly large graphics screen. Trying to boot CentOS out of boot menu boots to "rescue".

Have CentOS working in separate data partition (/mnt/data... data common to all 7 OS). Building custom menuentry's now. It's slow work for me (trying to... failing... trying again... breaking Manjaro... etc.) I've been gifted a custom menu format for CentOS... known to work with Fedora, Korora, others... theory says, will work.

I don't see CentOS working any better with other OS in UEFI menu or boot menu. I think the problem may, in part, be in CentOS /etc/default/grub. This is my unmodified /etc/default/grub:

Code: Select all

GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="rhgb quiet"
GRUB_DISABLE_RECOVERY="true"

I would change 'GRUB_DEFAULT=saved' to 'GRUB_DEFAULT=0', but I have no idea if doing so would break things... and don't know of a way to test the change safely. If you know if this will function, or not, would you explain please? If you know of a way to test the change safely, I would like to learn that.
