| nikolam | About resolution problems on VGA-1 output on HP 600 G1 i5 4570 HD4600 Intel graphics, when I changed the VGA cable with shorter another one, suddenly monitor automatically displays right resolution of 1920X1080 60Hz | 05:21 |
|---|---|---|
| nikolam | Aether longer cable was bad manufactured or shelded or some pins were not connected for monitor information to be passed to computer, or it was too long and/or signals too weak to pass through it properly (there were also some on-screen artefacts and blur, that is not present with shorter VGA cable. | 05:23 |
| nikolam | Interestingly, samo low resolution problem were present, when using VGA input to HDMI output powered adapter, resolution could not be properly set again, and now with short VGA cable all ok. | 05:24 |
| nikolam | Seems like Xfce Display settings tool have a problem setting display resolution that user requested, if not having available resolution information from the monitor itself.. | 05:25 |
| nikolam | I at least once managed to set right resolution with xrandr , by pushing it to higher resolution step by step so it seems it was possible to display it, just some control mechanism stopped it from working, probably not being able to read monitor data or something | 05:28 |
| xu-irc30w | Hi, I'm a newbie to Xubuntu and to this support forum. | 09:16 |
| xu-irc30w | I installed xubuntu on a Lenovo at the beginning of the summer. The mouse pad stopped working. I used an external mouse instead. Now I've just been offered updates, which I downloaded. Now the screen constantly flashes. With difficulty I can launch firefox, Thunderbird. But due to the rapid flashing I cannot use. The file causing the problem may be | 09:23 |
| xu-irc30w | titled beginning blue... Help plse. Thanks. | 09:23 |
| tomreyn | xu-irc30w: hi there, are you still around? | 10:41 |
| tomreyn | if so, are you using this chat on a different computer then? | 10:42 |
| tomreyn | can you switch, on the affected computer, to a TTY and login there? | 10:43 |
| tomreyn | !tty | 10:43 |
| ubottu | To get to the TTY terminals 3-6, use the keystroke Ctrl + Alt + F3-F6 respectively. Ctrl-Alt-F2 or Ctrl-Alt-F1 will get you back to your graphical login (Ctrl-Alt-F7 on 16.04). To change TTY resolution, see https://help.ubuntu.com/community/ChangeTTYResolution | 10:43 |
| tomreyn | after logging in, run this to provide some basic information on your system (this requires having Internet access): | 10:43 |
| tomreyn | nc termbin.com 9999 < <(lsb_release -ds;cat /proc/{version_signature,cmdline};echo "Session: $XDG_CURRENT_DESKTOP ($XDG_SESSION_TYPE)";echo Shell: $SHELL) | 10:44 |
| tomreyn | lspci -knnd ::0300 | nc termbin.com 9999 | 10:44 |
| tomreyn | apt list --installed | grep ',local\]$' | nc termbin.com 9999 | 10:44 |
| tomreyn | apt policy | nc termbin.com 9999 | 10:45 |
| tomreyn | those would return a coupld of http addresses with the outputs of these commands, and you could post those addresses here | 10:45 |
| tomreyn | these commands gather some information on your hardware and drivers. | 10:46 |
| tomreyn | here's another: | 10:46 |
| tomreyn | journalctl -b | grep DMI: | 10:46 |
| xu-irc30w | Thanks for the quick replies.Yes, I'm using an old Eee PC running xubuntu. i'll try what you suggest. | 11:02 |
| xu-irc30w | Hi Tom, the ctrl+alt+F3 etc give me a blank screen, but don't seem to accept any command. Ater a bit the screen flashes again revealing the xubuntu desktop. | 13:09 |

| xu-irc30w | Thanks for the help. I've managed to open the machine using grub and running an earlier kernel, and have recovered all my files! Relief. Now just need to pick thebest kernel for the time being. I suspect issue may be between Lenovo and Ubuntu. | 14:35 |
| diogenes_ | lenovo is one of the worst choices to run Linux on. | 14:38 |
| xu-irc30w | Yes, I fear you're right. I moved over to Linux to get rid of windows. When I bought it was what I could afford. | 14:54 |
| tomreyn | xu-irc30w: if you'd like more suggestion son what to try, i'd still be happy to review those command outputs. | 15:26 |
| tomreyn | to get my attention later, please write my full name "tomreyn". | 15:26 |
| tomreyn | if you lost the chat log, i assume this channel may log to https://irclogs.ubuntu.com | 15:27 |
| xu-irc30w | Grub-customizer allowed me to delete the update that introduced the issue and roll back to the previous stable version. | 18:01 |
| gnoob | Hello, I have installed Xubuntu and the Default Power management is to blank the screen after 10 minutes. However, whenever I come back to my PC the Display settings I had set are reset. For example Extending the screen instead of Mirroring. | 18:16 |
| gnoob | I have tried to do some googling but apparently I am not seeing much. | 18:16 |
| gnoob | Hoping someone can provide some insight as to what I might be overlooking. | 18:17 |
| tomreyn | xu-irc30w: remaining on an old kernel image won't provide security, though | 18:44 |
| tomreyn | you have a workaround, that's good. but you'll need to find a solution. | 18:45 |
| tomreyn | gnoob: i will not be able to answer this, but you should provide your xubuntu version (lsb_release -ds) and graphics hardware and driver: lspci -knnd ::0300 | 18:47 |
| gnoob | Ubuntu 21.04. Advanced Micro Devices, Inc. [AMD/ATI] Raven Ridge [Radeon Vega Series Kernel module is amdgpu. Here is the full information. https://pastebin.com/eVk2188Q | 19:09 |
| gnoob | I'll be back :) have to bail for a while.. | 19:48 |
