Posted: Sat Nov 25, 2017 1:40 am Post subject: [SOLVED]I'v followed gentoo handbook and have some questions |
|
|
I've installed on UEFI/GPT gentoo with arch linux iso.
And by using
Code: | #genkernel --menuconfig all |
I've configured my kernel.(followed handbook page on 'xorg','kde-plasma','intel' becaulse I have only intel gpu in my laptop)
When I finished installation, I added 'konsole'and 'google chrome'and changed package.license for installing google chrome.
Now, my laptop's youtube video, or plain web site text seems like less optimized.
(Situation: 1. youtube slows at full-screen.
2. youtube sound sync slightly doesn't match with screen.
3. when I'm reading text, there's some blur on screen, through 2~3 lines.(regardless of mouse pointer location)
those were not happened when I'm using other distos, and I'm assuming these were happening by something with video drivers)
What else should I do for my laptop optimization? or what else should I read for it?
Thx for reading

And What should I look for in log?
[Edit 0]
I found log at /var/log/Xorg.0.log and second question still remains. What is related with my situation among these?

No idea myself, but if jaglover wish look at it, he have something in mind, and at least you need something to start with.
Code: | [ 20.422] Kernel command line: BOOT_IMAGE=/kernel-genkernel-x86_64-4.12.12-gentoo root=UUID=f5ae869b-2318-4658-bc76-06a330680d81 ro pci=nomsi |
why do you disable msi? |

When I boot the system, there is infinite loop saying "PCIe bus error~..."
And I found "pci=nomsi"can fix this.
I've used that kernel parameter for 3months and fixed that problem.
Exactly same as this happend to mehttps://askubuntu.com/questions/771899/pcie-bus-error-severity-corrected |

But the problem is not there. It was fine with "pci=nomsi".
Do you think that can affect video performance even though it wasn't with any other distros? |

whjeon,
Xorg.0.log: | [ 20.526] (II) intel(0): switch to mode 1920x1080@60.0 on eDP1 using pipe 0, position (0, 0), rotation normal, reflection none
[ 20.532] (II) intel(0): Setting screen physical size to 508 x 285 |
Are you forcing a screen resolution?
Normally, Xorg prints a list of supported screen resolutions but not here.
If 1920x1080 is your native screen resolution, that's OK.
If its not, the edges in the image will look fuzzy, as its not possible to rescale one digital image onto a different resolution display surface, unless the conversion factor is a whole number
A 2560x1600 screen can display a 1280x800 image correctly. Each pixel in the image maps to exactly 4 on screen pixels.
It looks really ugly, as you describe, when fractional pixels are involved. _________________ Regards,

Yes, my laptop has 1920x1080.
And I'm assuming that this symptoms are caused by video related drivers.
But I cannot sure, because I don't know what to look for. |

I need more explain with that. I don't understand what is "modesetting" and "xorg.conf".
Do you mean, I should change my kernel configuration and boot with new kernel? |
