I quit Windows and installed Ubuntu, When I power on this error screen is showing!
error: no server is specified. error: no suitable video mode found. /dev/sdc2: clean, 259918/15630336 files.
After this error screen for few seconds it automatically boots into Ubuntu.
Need Help :)
Nothing to worry about especially if it boots fine and loads your graphical environment. It's just a grub warning message because grub doesnt play well with (presumably) nvidia. You could probably make some tweaks to remove the error but there's really no reason to bother.
As it boots fine (and changing into wayland later) I think you can just ignore it.

Let me guess, you have an Nvidia card?
Yes.
Red Dead Pixel Redemption.
I had this error several times (also cases where it would not boot afterwards). It usually appears after installing Nvidia drivers.
The first two lines seem like they probably came from X, the old standard UI system for *nix. The last line is just saying that your 2nd partition on your 3rd disk was checked with no errors found. This is fine.
Given that the UI then starts up you can ignore these messages. They're there in case the system fails to start up after that point.
GRUB (or any other bootloader) doesn't care about and in fact doesn't even know about X, Wayland, or any other userland GUI system.
Okay? These aren't from the bootloader tho.
X11 doesnt start until after the kernel is loaded.
Yes, that's right.
Did you install Ubuntu alongside Windows, or do a fresh install after wiping?
Its fresh install, no dual boot
According to DDG it's a Grub issue. There are a couple of things you could try by searching that error message.
What are your PC specs? Make sure CSM and Secure Boot are disabled in the BIOS.
Use Linux Mint instead. You'll thank me.
Avoid *buntu.
What did I miss? Ubuntu used to be the shit.
Forced Snaps is a big one. If you're not familiar, Snap is Canonical's proprietary alternative to Appimage and Flatpak. While the Snap Store is open source and can be forked or modified as needed, the backend is completely closed source, which has vexed many members of the Open Source community.
While the distribution itself is currently pretty solid, they've made questionable decisions in the past like including an amazon search function in their fork of gnome (Unity). Snap can be removed by a skilled user or someone well versed in search-fu, but their choice to have it installed by default, the be the default for package management, and to inject snaps in place of deb packages when installed via Apt, are all big red-flags given that nobody can see what is in those snaps til they're installed except for canonical.
I don't know about anyone else, but, I went from Kubuntu to Debian/KDE because I don't like seeing all the Snap-fake hard drives in lsblk.
It's the snap-less surpremacy guys.
Apparently this was a controversial take
When I first started learning how to Linux long ago everyone recommended Ubuntu... and I had a similar issue to the OP.
I had to dump the EDID of my monitor from a Windows machine to actually get X to recognise any kind of monitor modes ..it was an eye opening experience for a newbie.
Today, I still dont really like it for other reasons (I'd take Debian over Ubuntu any day). Call me crazy here guys but I think its okay to share an opinion without being called an edgelord for it.
(I use arch btw 🎩)
I've had a much easier time on Ubuntu with NVIDIA cards than with other distros. Also, I'm not sure how this is helpful advice to a new user at all.
