Copy its filesystem to a directory. Remove some stuff you can live without. Make another .iso file using directions for making a bootable disk.

Finally this may do better on a fedora mailing list (but they will ask the same questions). For a CentOS viewpoint I would ask if it happens if you run CentOS-8 (try via a live cd) on the box. If it does happen, then it is a problem between Fedora-18 and Fedora-28. If it doesn't happen then it is a problem between Fedora 28 and the version of Fedora you are trying. IIRC Centos 8 does not have a live version. Fudge, I should know that. Sorry for a wild goose chase. I would see if the CentOS8 installer goes into X with a larger than 640x480 I just managed to install to an SD card. Default Centos 8 gives me 1440 x 900.

[CentOS] installing Centos 8 to an SD card
I'm trying to install Centos 8 from a CD burned with Centos-8-2-2004-x86_64-boot , to an SD card in a USB SD card reader. The installer appears not to notice the card reader. Doing a df from tty2 also provides no notice of the card reader. Can what I am trying to do be done? The card currently has a German Knoppix on it.

I've been trying to write X configuration files to tell fedora 1440x900, but no joy. Is there a way to get X to tell me its current beliefs, very preferably in configuration file format? According to the log file on Centos, everything was defaulted or probed. It contains no numbers. My guess is that fedora has different defaults and they are wrong for me. I've had problems like this before, so I'm unwilling to install until I know I can run a live version. That makes life clunky.

Re: [CentOS] Encrypted container on CentOS VPS
What is the use-case here? Are you concerned that the host may change the data or just read it? Would re-creating the file anew for each use be practical? What about using the file in an encrypted form? I'm thinking of the case of records on people. Separate "cyphers" for first names, last names and other names would go a long way toward hiding whatever needs to be hidden. Keeping the host from reading the data might not be a solvable problem. Keeping the host from quietly changing the data might be expensive. If all else fails you might keep copies of the data on separate hosts and compare their md5sums. I expect that doing it on your own host has already been deemed a failure. -- Michael henne...@web.cs.ndsu.nodak.edu "Sorry but your password must contain an uppercase letter, a number, a haiku, a gang sign, a heiroglyph, and the blood of a virgin." -- someeecards ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

How can I fix this so I do not have to manually edit resolv.conf after each reboot. Neither of those files are the correct files to edit. You want to edit the ifcfg- file (replace with the name of the network interface) and add PEERDNS=no in the file. This will make it so DHCP doesn't overwrite the resolv.conf. I only have ifcfg-lo , which I am pretty sure is the loopback interface. As expected, other files suggest eth0 is my ethernet connection. Should I add a one-line ifcfg-eth0 file? If you just want to hard-code DNS servers, you can either do that in your networkmanager configuration, or add DNS1=9.9.9.9 to the ifcfg file. You can add a second IP with DNS2=1.1.1.1, too. Use whatever DNS IPs you want. What I want is to keep midco from hijacking searches. Keeping midco's DHCP from adding a search line to resolv.conf seems to be the key. I'll hard-code DNS servers if I have to, but that is not the point of this. Currently I have # Generated by NetworkManager # search midcoip.net nameserver 2001:48f8:3004:2ce:5a19:f8ff:fe9e:a4bc nameserver 192.168.0.1 My understanding is that the network manager generates resolv.conf and DHCP edits it. Does the network manager include nameservers? Would putting PEERDNS=no in a ifcfg-eth0 file result in an empty resolv.conf ? I realize I could just try it and see, but I do not know how much damage I could do if I mess it up.

It's a GUI, but you can start it from a command line in a GUI environment (i.e. it's not a command line program).

It's RAM. You basically have a total of 2G ram on the system, you have less than 500M available and are into swap by nearly 1G, so you're swapping heavily. 2G is enough for a minimal install but browsers such as firefox and chrome can easily use a lot of memory fast and trying to run one on a 2G system while doing an install at the same time will get you swapping and slow the system to a crawl. To be clear, by "Centos 7 installation", I meant a PC on which Centos 7 was installed. In any case, Centos 7 has not always been this slow. Presumably something has changed. I've been living with this for several months, but not forever. I can run compilers and stuff without an internet connection, so I could get some work done.

[CentOS] browsers slowing Centos 7 installation to a crawl
My video problems mentioned in a previous thread are gone, though I do not know why. Now my problem is that whenever I have a browser open and an internet connection, my Centos 7 slows to a crawl. Chromium seems to be the least bad. Sometimes it slows to the point that I cannot even move the mouse. Even switching between virtual terminals takes a while sometimes. When I get there, top generally shows me between two and five D states. I've changed service providers lately. The problem survived the change. Some sites seem to aggravate the problem. Most recently, a site tried to connect to c.amazon.adsystem.com . I got the message waiting for c.amazon.adsystem.com . I have that address in my hosts file as 127.0.0.1 . ping finds it and pings. nslookup does not: [hennebry@localhost ~]$ nslookup c.amazon.adsystem.com Server: 192.168.0.1 Address:192.168.0.1#53 ** server can't find c.amazon.adsystem.com: NXDOMAIN Whether the slow-to-crawl problem is related to the failure to redirect, I do not know. The former is clearly more important. Any suggestions on how to diagnose it?

I keep finding claims that Fedora live CD's exist, but not actual images. I did find a C6 live CD. No go. Without additional installs, it would not even try. After accepting its offers to install dragon and totem, it still would not play any videos. ... not working falling back to default. The default was blank. It would not do videos at all. It claimed it did not have mp4 codecs. It made the same complaint about avi and flv files. That's mainly because they are non-free codecs so aren't included by default. To be clear: flv and avi caused it to complain about the lack of mp4 codecs. Is there something dragon or totem will play out of the box? -- Michael henne...@web.cs.ndsu.nodak.edu "Sorry but your password must contain an uppercase letter, a number, a haiku, a gang sign, a heiroglyph, and the blood of a virgin." -- someeecards ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

And your chipset is not exactly cutting edge stuff. I bought it used. Are there any errors in the logs - either kernel logs or X logs? I'm not seeing anything that seems very interesting. Xorg.0.log uses the phrase "falling back" a few times. I expect that just means I've not inerfered with defaults. boot.log-20180625 does not contain any of the sequences rap, RAP, ideo, IDEO. dmesg contains graphics and video, but nothing that seems interesting. For some reason you say you disliked Gnome - but does Gnome show issues (they use the same video driver)? I'll try it. A long shot is the theme. Are you using some non-standard theme on your desktop? What is a theme? Finally, do you have a spare graphics card you could try in the machine? (This is just to make sure there's no hardware problem.) Only as a last resort. Having already lost a couple graphics cards (not in this machine), I open the case rarely and with fear and trepidation. When I hover over text, the black tape effect goes away. Do graphics cards know about text or hovering? -- Michael henne...@web.cs.ndsu.nodak.edu "Sorry but your password must contain an uppercase letter, a number, a haiku, a gang sign, a heiroglyph, and the blood of a virgin." -- someeecards ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
