Hello, I am new with linux. I installed Fedora KDE plasma (spin version) on a PC that I just mounted with intel core processor i3 UHD graphic 630 and the display on my screen is deplorable ... The text "drool" and the dimensions in the web browser are too small. I have a screen of 1920x1080 Asus LCD.

I tried a lot of settings (4 days!) And asked for help at the French forum Fedora, but we do not find the solution.

Here are my font settings: Everywhere : -> Droid Without [MONO] 10, except fixed Monospace 10. Use Smoothing: On, Subpixel rendering type: RGB

Optimization profile: Light

And to find an acceptable size: Force PPP: 120

I also tried to adjust the monitor, but without success ...

I also have too much padding and not exactly the same proportions in my websites (I'm web dev.) which will cause me a problem to work and have the same rendering as my clients, all on Windows.

It's a shame because I think Fedora + KDE plasma is a very modern interface and it is ahead of all the other OS at all levels in my opinion ... except for the display! Just in my case because other users are raving about.

I had hangs with Workstation to allow auto login, Worksation crashed and never restarted, bad password message (but I typed the right one) I'm pretty comfortable with the terminal, serving me a bit of Node and NPM under windows, I managed to auto login and numlockx on my version, it works.

Thanks for your help, Regards, Raf

more : in /etc/X11/xorg.conf.d has no intel file, inxi commabd do not run -> "Not found"

-> can be a driver problem ??

NEW : install inxi this give -> inxi -G

Hi, unless you want to change some settings, xorg config is not necessary. From what I see, you're using modesetting - in most cases it works better for Intel hardware.

What's the size of your screen (in inches)?

Hello everyone and thank you for your follow-up!

I re-installed my cg nvidia GT 220 to get a smooth text and web content proportions on windows 10, the built-in CG processor did not have a definition at the top and the display was also very small and a can baveu ...

So, I think I'll have to test Fedora with a graphics card but in the French forum, they also told me to try without a graphics card and with Wayland installed, I currently have X11 (see: inxi - G).

I would try all this after filling the fridge ... within 3 weeks, if you want to see the subject in the French forum follow his address:

HI Raf.have a fun! Basically, it is not advisable to add a graphics card to solve the problem, but I think it is a idea to add a graphics card if you have a problems. The advantage of a graphics card is that it reduces the CPU performance of built-in graphics and improves system performance due to shared memory. However, fundamentally adding a graphics card is not the perfect solution as you and other respondents say @ozeszty Nevertheless, if you can not solve a particular environment and system problem, I think you have the above advantages and can solve the problem more easily

Hi, I'm new to Linux ... I see the site that you indicate me but I do not know what to do next ...

Everything is up to date on Fedora.

I really do not know which driver to download, I took this driver: NVIDIA-Linux-x86_64-340.107.run But I do not know how to use it, Thank you for your help ...

I just mounted a PC but I did not want w10 ...

Don't install anything outside of Fedora repositories for now, at least not for Intel GPU (Fedora has newer drivers than what Intel provides on https://01.org/). You've got only Intel GPU, so Nvidia driver is unwanted.

What's the size of your screen in inches? It's so we knew what kind of scaling you need.

Hello, thank you for your help!

The size of my screen is 24 inches (60cm). Apparently, I would not get a good display without a graphics card. Dimensions and text are too out of sync to work long on my PC.

I installed windows 10 and except that the scales are too small, the text is clearer (much clearer) and I have no problem viewing videos because I could not watch some videos with chromium. .. But here too, a GC will be mandatory I think.

Linux is really too complex to configure on some things, for others, I really regret it.

I would have liked to insist more but I lost a week of work over a weekend to try to overcome and I stopped the computer a good dozen times during this period!

As I am dev. Freelance web I can not afford to devote more time and the small differences in padding and size I met did not please me ...

Again, the display was sorely lacking in contrast which is very painful when working with the console + Atom always open.

I would continue to follow this topic because, as I said above, Fedora + Plasma is one of the most beautiful environment I have ever seen ...

The appearance and philophy of the OS are at the top ... By cons it is certain that novices in computer will never enter a terminal or many things pass through the terminal.

Thanks a lot for your help, see you soon, Raf

Hi, links that @simmon provided you with are old and mostly irrelevant for Fedora - Mint is based on Ubuntu LTS and has much older components. You also don't need another GPU for your computer to work, I tested Coffeelake laptop last October and Fedora KDE worked well there.

For better contrast you should try other themes, either system wide for Plasma (System Settings -> Workspace Theme -> Dark Breeze or Breeze, if you prefer lighter colours) or just for Konsole (Settings -> Edit current profile -> Appearance).

For better readability I also disabled sub-pixel font rendering: System Settings -> Fonts -> Fonts -> Use anti-aliasing: Enabled; Sub-pixel rendering: none; Hinting: change to your preference.

plasma-applet-redshift-control is a must-have if you work late.

24" and FullHD is pretty standard combo, you shouldn't need any scaling or tweaking (e.g. DPI) for regular sizes.

I'm using Fedora Cinnamon with default font sizes on 23,6" FullHD display. All websites I create here have no issues with sizes, whatever I see in Firefox or Chromium is consistent with other systems and screens. Firefox's Responsive Design Mode works well for previewing other devices. Just keep in mind that other systems come with different default fonts.

Right now looking at Cinnamon on 23,6", Plasma on 24" and Win 10 on 15,6" HD screen side by side, I see no spacing or font differences on same website (other than those resulting from different DPI/PPI). Well, colours are better on 23,6" screen, but that's because it's a cheap IPS and the other are crappy cheap TN panels ;)

So my advice is:

make sure Fedora and BIOS are up to date;
create fresh system profile, look at settings I listed and re-evaluate;
restore monitor's factory settings, check available pre-set modes or start tweaking it again.

If issue persists, catch it on a photo and show it to us. Maybe you're used to some unusual scaling/settings?

@ozeszty In my experience, if there is a problem with the built-in graphics, I have solved the problem by installing a graphics card for graphics problems and using it until now.

I use the F29 Server KDE and I am using a 24 inch monitor.

If it is difficult to solve all the problems under certain circumstances, it is also a good idea to find other alternatives.

@simmon, Adding another GPU is a workaround, not a solution. When did you experience those issues? Have you checked recently if they were still occurring on your iGPU?

Intel messed up with Coffee Lake, even though it's GPU is no different from previous generation, they forgot or missed adding some PCI ID to drivers, hence the issues. This was fixed throughout last and even this year, and should be in current F29. There were also many improvements and bug-fixes along the way.

So, those issues are fixed, and the ones @Raf-sns encountered (totally different), are addressed in my answer.

@ozeszty

I do not think any device can fully support the operating system.

I spent a lot of time and answered through the experience that I have, which may not be the perfect solution to a problem.

I think adding graphics cards can make it smoother than systems for high-resolution graphics like Virtual OS and KDE. However, power consumption should be considered.

If I can not solve the problem for a specific purpose, adding a graphics card is one of the solutions. It may vary depending on your situation, but ...On a typical primary server I do not add a graphics card. However, I think it is necessary for a virtual server or a management server.

simmon ( 2019-03-10 10:00:24 -0600 )edit

I'm not saying that adding another GPU is generally bad idea. If troubleshooting time will cost more than a proven to work GPU, or if you could use additional capabilities offered by an extra GPU, it's a smart move to buy one. It might have been best choice for you, year or months ago, but it doesn't mean that today my answer is wrong.

From what I've read here, @Raf-sns issues, most probably, come from misconfiguration.

I've got Plasma running on 10 years old Intel iGPU. It's lighter than it seems with all the bells and whistles. And I've seen it work well last October on a CoffeLake laptop.

P.S. Selected Broadwell (5th generation Intel Core) and newer processors supports GVT-g for GPU accelerated VMs: https://wiki.archlinux.org/index.php/...

There is a lot of content related to Linux, and the graphics show that Intel supports Linux.

 https://forums.linuxmint.com/viewtopic.php?t=261389
 https://www.reddit.com/r/linuxhardware/comments/7v6sdr/intel_uhd_graphics_630_support/

Intel say,,,,in official Web site - Linux Support Intel UHD630 [Intel CPU - Coffee Lake] However, the operating system that provides the driver for use is Win10 and Linux is also supported,
The Intel graphics support web address for Linux is:

 https://01.org/linuxgraphics

Linux support file is provided to compile and operate in the kernel and specific environment. Perhaps because it works in a limited kernel environment, it seems to be valid in older kernels and may not seem to work perfectly on F29 with the latest kernels. In some cases, it may not be fully supported by Linux, and not all features may be available. However, after a while I think that it will be able to fix it with the driver and support.. Can you try using the appropriate driver and tell us the status and progress?

A. Check the following commands for using and installing the graphics driver.

$ lspci | grep VGA
$ rpm -qa|grep xorg |grep intel

B. Check xorg related programs for graphic use and installation? No system can support a complete device. However, since the cpu supports graphics, it is limited to a specific environment, so if the number of users increases, the device can be supported by Linux.

It also works on certain kernels, as long as the device supports running on Linux. So, in the case of Linux, many people use it, and installing it using a compatible device will save you the same trouble.

C. By replacing the built-in CPU support graphics by adding a compatible graphics card, you can easily solve the problem. Basically, it is not advisable to add a graphics card to solve the problem, but I think it is a good idea to add a graphics card if you have a lot of time and problems. The advantage of a graphics card is that it reduces the CPU performance of built-in graphics and improves system performance due to shared memory with the System

However, fundamentally adding a graphics card is not the perfect solution as the questioner and other respondents say @ozeszty. Nevertheless, if you can not solve a particular environment and system problem, I think you have the above advantages and can solve the problem more easily.

It should be installed initially with a device that has been proven for 1 to 2 years longer than the latest hardware, and should not be changed as much as possible after installation.

D. In my experience, if there is a problem with the built-in graphics, I have solved the problem by installing a graphics card for graphics problems and using it until now. I use the F29 Server KDE and I am using a 24 inch monitor. If it is difficult to solve all the problems under certain circumstances, it is also a good ... (more)
